3157/7443 CK VS. STANDARD SOCKET

What is a CK/SRCK socket?

A CK/SRCK is like the traditional sockets you see in most Japanese, and American vehicles except the ground terminals are located on the same side of the socket.  If the ground terminals are located on the opposite side of the socket, then it more then likely is a standard socket.  We still encourage you to test the sockets using a multimeter.  To identify the ground positions.

Standard Socket

What will happen if a standard LED bulb is used for a CK socket?

Only one level of brightness(intensity) will light up, and when the other application is activated, it will cause a short on the circuit.

How to distinguish between a  CK socket and a standard socket?

From our experiences, most TOYOTA vehicles front turn signal sockets are a CK type.  Sometimes, you can even see there are two terminals connected directly, which means they are the ground terminals.  You may also identify the ground terminal location from the wires on the back of the socket.  A test is still required, using a multimeter, in order to confirm the type. Also your original bulb will tell you if it is a CK or standard, most CK bulbs will say SRCK on the bulb base.

Why do I have a standard halogen bulb, but a CK socket?

The ground pins of halogen bulbs are not shared. The ground pins of LED bulbs are connected on the circuit board inside the LED bulb. The circuit board is necessary to help maintain the temperature of LED which will provide stability, and a long lifespan.

How to solve Turn Signal Light Hyper-Flash

Did you just purchase LED bulbs for your turn signals, installed them and now is wondering why it is flashing really fast?

Well the reason is LED lights draw about 5W of power, which is much less than that of a halogen bulb(27W~30W).  An error code or hyper-flashing is a malfunction that will come up to notify the driver when vehicle detects a change in the power draw.  The vehicle is recognizing the upgraded LED bulb as a faulty (burned) halogen bulb due to the low power consumption

Below are the solutions we recommend that will fix any error code, hyper flashing, flickering issues that you may run into.

SOLUTION ONE: Plug n Play Resistors

3157-5 installation

 

We have made plug n play resistors for different socket types, ex. 7440 7443 3157 3156 etc. These plug n play resistors are very convenient due to the fact that there is not splicing or tapping of any of your OEM wiring. This will be the simplest solution to solve your hyper flashing issue.

PLEASE NOTE: Resistors will get hot, when installing resistors please keep them away from any plastic or wires.

The power of load resistors is 24W@12V  24W+5W=29W, nearly the same power as a halogen bulb

 

SOLUTION TWO: LED Flasher Relay

EP29

This LED flasher relay will replace your original flasher relay. Here at JDM ASTAR we have made this product for customer who do not want any resistors near any wiring or plastic, so this would be the best alternative for those customers. With this relay it is a direct replacement for certain vehicle makes such as Honda, Volkswagen, BMW, Mercedes-Benz, AUDI, etc.

The LED flasher relay is very similar to the resistor, it regulates the power and tricks the vehicles system to prevent the hyper flashing with the LED bulbs.

 

 

SOLUTION THREE: Universal Load Resistors

50W 6ohm load resistor

These Universal 50w 6ohm resistors will work for any vehicle to fix error codes and hyper flashing. With the universal resistors tapping or splicing is required. To install these resistors you would need wire taps. Most people will tap the rear turn signal wires instead of the front due to weather conditions or road conditions that may affect the resistors.

The universal resistors will help prevent any flickering issues, hyper flashing, or error codes by regulating the power draw to the circuit. These will work with any vehicle that may need it, installing these may be a tad bit difficult on some vehicles depending on how much space they may have.

To install these resistors you would need to tap the ground wire and the turn signal wire, for some vehicle this would be really simple to find since the rear turn signal has 2 wires. For the vehicles that have more than 2 wires in the rear turn signal you would need to use a test light and test which wire is the turn signal wire. After finding the wires and tapping them, you would need to mount these resistors away from any plastic or wires due to the resistors getting extremely hot and may cause damage to the vehicle.

PLEASE NOTE: RESISTORS WILL GET HOT!!! KEEP AWAY FROM PLASTIC OR WIRING

3030 Series coming to a turn signal near you. . . .

Have you ever purchased a set of LED bulbs to upgrade any application in your vehicle?  You went for the biggest, ‘baddest’, and brightest LED light available and got amazing results, but you also only got a few days of life out of it.  Either your bulb is dimming, flickering, or some diodes are not lighting properly.  Whatever the case, the issue could have been due lack of proper heat dissipation since LED is prone to failure at high temperatures.  Look no further because JDM ASTAR just released a new product that not only offers performance results, but endurance!

Our latest addition to our LED lineup is our 3030 series.  Our 3030 series is capable of producing up to 1500 raw lumens per lamp at a color temperature for 6,000 kelvin for a highly visible, xenon white look.  They are also available in other colors like amber, and even a switchback version for the car enthusiasts!  It features a glass lens projector to help concentrate light towards the lens of the housing assembly.  This will, not only improve your driving experience, and safety, but will also give your vehicle the elegance it deserves.

The body of the bulb is made with an aircraft grade aluminum and has been redesigned to increase rate of heat dissipation.  The 3030 light emitting diodes are mounted on to an aluminum board, which is connected directly to the body of the bulb.  This will push the rate of dissipation even further by up to fifteen percent!  The built-in IC ‘constant-current’ driver also plays a role in maintaining temperature since it regulates wattage to each diode and ensures the proper amount power for high efficiency and stability. This will allow your bulb to run cooler for longer periods of time, without a worry of causing any heat stress to the diodes.  This will, in turn, provide a longer life span than a standard LED bulb without a cooling method.

The unparalleled design on our 3030 model also makes this LED bulb suitable for turn signal sockets that have a different configuration.  The non-polarity feature allows this bulb to function properly with sockets that have a CK/SRCK or standard configuration.  You will be able to upgrade your turn signal application without a worry of blowing fuse, or the hassle of testing the sockets, with a multimeter, that you probably do not have.

With how the 3030 series is designed, it makes this LED bulb suitable for a variety of lighting applications.  They are available in different bulb sizes ( 3157,4157NA,7443, 7444NA,1157,7528,etc.),  color, and are designed to replace stock halogen bulbs(20W-27W) for your fog lights, turn signals, back-up lights, brake and tail lights, daytime running lights and even parking lights.  Visit Here for more information on our 3030 series, and remember, time is money!  Invest your time properly and save money on a set that will provide longevity and performance.  Think endurance, think brilliance, think 3030. . . .coming to a turn signal near you!

LED bulbs not lighting up?

We have all been there, we purchase bulbs from online sellers, and once we get them in we are full of joy and excitement and ready to install. Some of us have installed some bulbs and find out that they don’t turn on, so we start assuming that they are defective and start having a huge disappointment. Now before you go and complain to the seller or give negative feedbacks, here are a couple of ways to troubleshoot your “defective” bulb.

 

STEP ONE: Rotate the bulb 180 degrees.

This step is the simplest way to figure out if your bulb is defective or not. You simply just rotate the bulb 180 degrees to see if the bulb will light up.

Now you may ask why it is necessary to do this, well most LED bulbs are polarity sensitive, which means they will only work when the positive pin matches up with the positive side of the socket/plug you are putting the bulb into.

STEP TWO: Bending the pins

This step is also an easy way to figure out if your bulb is defective. Bending or moving the pins more outward will help ensure proper connection with the socket. Sometime the bulbs base will be too narrow to the point where it will not make any contact at all, with a little modification with the pins on the bulb, you will have a nice snug fit and good contact to ensure that the bulb works perfectly fine.

STEP THREE: Put back your original bulbs

If both steps did not work out for you, then you will move on to this step. It is another simple solution, put back your original bulb in the socket to see if it lights up. If the original bulbs light up then you can come to the conclusion that you have received a defective bulb, if the original bulbs do not light up then you would need to check your fuses or check the wires to see if there is any power going through the wire. Checking your fuses will be explained in the next step.

STEP FOUR: Checking Fuses

Checking fuses is always a solution to a lot of wiring or power issues that you may have. When the first three steps are not helping, this option would be sure to help you figure out why your bulb is not lighting up.

There are multiple fuses for almost everything in your vehicle, if your bulb is not lighting up this may be the reason why, you may have a blown fuse. To check which fuse you would need to pull or check, you would need to go to your owner’s manual and find the fuse box locations. Once you have found the location of the fuse box, this is where you can see which fuse controls what. Then once you have found the fuse that you are looking for, pull it and then you will be able to see if it is blown or not. If it is blown, replace it with the same amp fuse(NEVER use a high amp fuse) and test the bulb again.
