Why is your LED lamp failing?

We have heard this issue before, and we believe that we can speak for every automotive LED sellers that they have come across a similar situation.  So, why is your LED bulb failing prematurely when it is supposed to last a lot longer than your factory halogen bulbs?  There may be several factors that could cause your LED bulb to fail prematurely, but the number one (and most common) reason is usually due to heat.

John Goodman LED meme.jpg

When LED made its way into the automotive industry, there was not that many options available.  The overall light output just did not make sense for the investment and not to mention, it lacks the innovations we have today.  Now, LED has made its foot print in the automotive industry and is slowly climbing up the ladder to reach its peak in the automotive market. You may improve the light output of your vehicles application (like a backup light) at half the rate of power consumption with double the light output for less than what a traditional halogen or incandescent bulb would cost you.  (Now, you can really start getting the light output that you need and/or desire and save money while you are doing it. Who doesn’t like to save money?)

Now that the brightness is up to par, heat generation is now the concern in the automotive industry for LED lighting.  We have learned that having a balance between light output and rate of heat dissipation will provide a long lifespan with your LED replacement bulbs.  Just like a computer part, LED has always had a threshold with heat.  LED is definitely an upgrade for any automotive vehicle, but it is susceptible to failure at high temperatures so having some type of cooling mechanism is always recommended.  We have also learned that there are other factors that play a role in the maintaining temperature of the LEDs.  We know that drive power will increase light output but will also spike the heat generated from the diodes.  Limited or small housing assemblies may also cause your bulb to heat up to a temperature higher than it can handle and cause the bulb to show symptoms of failure.  For example, if you install a standard low light output LED bulb to side mirror application, it will definitely provide brighter results, but if the bulb is a high power LED with a high lumen rating, then it may not be the best idea.  The fact that the housing is very limited, in space, it builds up the heat faster and does not allow any cooling.  This, combined with the amount of heat generated, may cause your lamp to begin to fail prematurely.

Just like your car engine, your LED bulbs have a threshold.  If you put a super charger, or turbo into your engine, it will work harder, and faster, but will also put wear on the internal parts of the car so it will cause the engine to not last as long as it was intended.  You will then have to service the engine.  Like your engine, LED also has a limit or threshold as to how much it can handle.  As long as there is a balance between heat dissipation versus heat generated then you will have a long lasting LED bulb.

Next time you are in the market to replace a bulb on your car, you should always take into consideration how your housing is designed, light output (wattage will also determine heat generated), and the LED housing. (Does it have an aluminum body to radiate heat from the light emitting diodes?)

 

Here at JDM ASTAR, we do not believe in limits.  Every day, we are learning new ways to redesigning our products, or integrate other parts like an aluminum boards to improve efficiency, and reliability.  We believe in pushing the threshold of automotive LED.  We are always trying to push our products to the limit and looking for new ways to remove the barrier that heat has created for everybody in the automotive LED lighting industry.

 

So, if you need to replace a factory, or a failed LED bulb, do not just aim for the brightest, but aim more for an option that will provide a balance between power, and reliability. . . . An option that only JDM ASTAR can deliver so that we may continue to light your way on the road. . . .

Changing the game in back up lights!

 

You have heard it many times, and you will hear it again.  “Why do car makers put such dim bulbs in their cars?”  Look no further because JDM ASTAR is at it again.  We have a huge line up of LED back up lights to help rid of those tedious 15W factory bulbs that emit less light than your smartphones camera light.  Yes, we said it. . . .SMARTPHONE CAMERA LIGHT!  We have seen back up lights not shine properly to where it makes it difficult, not to mention unsafe, to reverse your vehicle. 921 GX 3020.jpg

JDM ASTAR has just released, yet, another option that will change the game in how you reverse your car.  Our latest addition to back up lights is our 921 GX 3020 LED.  Most vehicles use this bulb size for back up lights, but for those that use other T20 or T25 wedge sizes, we still have other options that will improve your experience while reversing your car.  The 921 GX3020 is changing how light is distributed, and how heat is dissipated.  The GX series offers the latest in heat dissipation technology.  It features, what we like to call, Cross Heat Dissipation (HD) which is located at the center point of the bulb where temperatures reach the highest.  Since LED does not operate well under high temperatures, the Cross HD allows for maximum heat diffusion.  This means a steady and cooler temperature to allow over 20,000 hours of life (in 25°C).  When the LED bulb is fired up, the center point is where temperature immediately begins to rise and with an integrated Cross HD, you will not have a concern for a heat failure.

921 GX 3020 2.jpg

The GX 3020 series is also one of the brightest we offer in back up lights with a xenon white color temperature(6000K-6500K).  Out of the box, they will emit over 1000 raw lumens per bulb with 13-SMD (surface mount diodes) high power GX-3020 chips.  Combined with a 5-sided setup, you will not only have a strong light emission, it will also provide you with proper light distribution.  You have to remember, your vehicles housing is built-in around a factory halogen bulb which shines light from practically every side of the bulb so using an LED replacement, such as the GX-3020, will provide similar light distribution for optimal results.  So, the lights bright, and works well so nothing new, you might say, but wait . . . . . there is more!

For those that drive motor vehicles that have a very ‘picky’ electrical system and simply rejects the lower power draw of your LEDs, you can still utilize the GX 3020.  Like our 921 PX model, our GX series also come equipped with resistors to simulate a larger power draw to allow the bulb to be detected, and therefor making it a, CAN bus ready, or Error Free LED bulb.  This means that the power draw (W) will slightly increase so that the vehicles system can detect it and prevent minor malfunctions such as a dimming, or flicker that are caused by the system.

Now that you know a little more about the GX 3020’s, we are not going to tell you to pick up a set for yourself.  We believe the 921 GX 3020’s speak for themselves so we invite you to change the world in how drivers back up there motor vehicles.

I bought the LED lights for the backup reverse lights and it is dimmer than my stock, is that ok?

It should be ok because the backup reverse lights are meant to alert others so they know there is a car is reversing rather than actually illuminating the road. Also if you are unhappy with the output of the bulbs you can contact us and we can recommend a brighter option for you. Back to Top


Why do my LED turn signal lights hyper flash?

When your LED turn signals flash rapidly, that is known as “hyper-flashing”. The rate that they blink is roughly twice than the normal flash rate. This is because when you replace the stock turn signals with LED bulbs; due to their low power draw, the regular rate of power being given to the lights is more than enough to light them up which speeds up the blinker process. Although this will not damage your vehicle nor the LED bulbs, some people may find it a distraction and may want to have it blink at the regular rate. To have the LED bulbs blink at a regular rate, you would need to purchase load resistorsBack to Top


>What’s a switchback LED bulb?

A switchback means it has two colors (White and Amber) which can switch back and forth. It is commonly used to replace the double-filament bulbs for the front turn signal lights which can function as both parking position lights and turn signal lights. So this way you can have the parking position lights in a HID matching xenon white color and the turn signal lights in a street legal amber yellow color.

To sum up in order to install the switchback LED bulbs, you will need to make sure your front turn signal lights function for both turn signal and parking lights and the lens needs to be clear.     Back to Top


What is SRCK socket?

Please take a look at these two diagrams below. The conventional socket has positive terminals on both sides but the SRCK socket has positive terminals on the same side. So a non-SRCK compatible LED bulbs installed to a SRCK socket will cause a short resulting fuse-pop or even damage the LED bulb.However, don’t worry because JDM ASTAR LED bulbs are mostly SRCK compatible. Please check the notes before purchase to confirm whether CK compatible or not.

Which LED bulb should I use for my fog lights?

You would be able to use any LED bulb you would like as long as you get the correct size, if you are looking for functionality then we would recommend one of our headlight LED bulbs, if you are looking to just change the look of it and not care too much about how bright it is, then any bulb will do. Back to Top


Do I need resistors or decoders for LED fog lights?

This will all depend on the vehicle, some vehicles requires resistors or decoders and some will not, in most cases, american, german, korean, european, etc vehicles will require decoders or resistors due to their canbus system.  Back to Top


My new LED fog light bulbs are flickering what do I need to fix it?

If you are having flickering issues with your fog light bulbs then you would need resistors installed, also a relay harness will work as well since the relay harness will be drawing power from your battery instead of the circuit of the OEM fog light plugs. Back to Top


What color is legal for my vehicle?

Generally the only colors you should be using is either white or yellow, you would need to check with your local state laws to see what color lights are legal for fog lights.  Back to Top


How do I fix or remove condensation within my fog light housing?

If you have condensation within your fog light housing, this may mean that you have a crack or some sort of damage on the fog light itself. If you happen to see damage, the fog light housing must be replaced or the problem will keep happening. If you do not see any damages, you can remove the bulb and use a blow dryer to dry out the housing, once dried check your bulbs o-ring to see if it is worn out, replace the o-ring if needed. Back to Top


How do I know if I need resistors or decoders for my fog lights?

To find out if you need resistors or decoders for your fog lights is by removing ONE bulb and turning on your car and turning on your fog light, if you see any warning signs on your dash board or codes then you would need resistors or decoders.  Back to Top


>I installed your bulbs and now they do not turn on?

If you are having issues with the bulbs not turning on, we first would highly recommend checking your fuses, if the fuses are good next we would recommend putting back the stock bulbs to see if they light up, if they do light up then the bulbs may be defective, however we recommend installing the bulbs with resistors first before declaring the bulbs defective. If all else fails, please contact us right away and we will be able to assist you with any issues you are having.     Back to Top

What is the difference between polarity & non-polarity?

Many led bulbs in the market are polar sensitive, it requires the led bulbs positive must connect with 12V power positive or it will not light up.

So for the polarity bulbs, if the bulb doesn’t light up, please flip the bulb 180° degrees and try to install again.

Yet for the non-polarity bulbs, you will not worry about this polarity issue. no matter how you connect the bulb into the original socket, it will light up.

Most of our miniature bulbs are non-polarity bulbs for we have made a great improvement to make it more easier to install for the customers. Back to Top


How to tell which bulb is the brightest and best?

Usually for led bulb brightness, it is calculated by the light output lumens, the lumens is higher, the bulb bulb is brighter.

Yet please note, when you care of the lumens, also please care of the heat dissipation, for many led bulbs are bright in the market, but easily burned out,because the heat dissipation is bad.

Our miniature bulbs are built in IC driver to control the stable current, and built in better heat dissipation,which will makes the bulbs’ life span much longer.Back to Top


>What is a led bulb’s life span?

Logically, if the led bulbs works in perfect condition, it will last up to 50,000 hours, yet due to different factors , such as heat, voltage, weather, vehicle usage, or other factors, will shorten the led bulb’s life span. But usually the led bulbs will work about 20,000 hours in average.      Back to Top
