Car LED Bulbs - FAQ & Troubleshoots

Why my LED is not working?
Even if you installed the LED correctly on your vechicle, there are a number of reasons why it does not work. Here is a list of things that you can check.
We ask that you follow these troubleshooting tips first and if your LED lights are still not working, please contact us.

    • Check the fuse box on your vehicle to ensure thet a fuse has not blown.
    • Install the LED on another vehicle to see if it works there.
    • Alternatively use another 12V power source to test the LED.
    • LED bulbs are polarity sensitive, remove bulbs and turn it 180 degrees to see if that works

If you have an Audi, BMW or VW vehicle with CANBUS, then place your original OEM bulb back in the housing, turn on your vehicle for five minutes to insure that your lights work. Then turn off your car, remove the key and replace the bulb with the LED.

My LED is working but I'm getting a bulb faliure error massage?
As the LED draws far less power than standard filament bulbs, some vehicles may create a false error massage when LED's are fitted.
To fix this you will need to install additional load resistors together with your LEDs.
The correct load resistors are available on our website.
Alternatively you can use special CanBus compatible "error free" LED bulbs,
but in this case some vehicles may still get an error and will require additional resistors to be fitted

Do I need to remove my battery or shut off my vehicle when installing LED lights?
You do not have to remove the battery of your vehicle, we do advise that you turn off your car and pull the key out of the ignition. This is especially true for Audi, BMW and VW vehicles that have the CANBUS in which the car cycles to check for light out errors.

Is “polarity” important in installing LED lights?
Yes, it's important to install LED bulbs with correct polarity, otherwise they will not work.
If this happens remove the bulb, turn it 180 degrees and put it back.

What are the “contacts” on an LED light?
The contacts are the metal pins or prongs on the base of the LED bulb (ei. the end that goes into the bulbs holder) that come into contact with your vehicle’s electrical system. It may be necessary to adjust the contacts located in the bulbs holder to ensure a good connection with contact on the bulb base.

Why I'm haveing a problem with my LED turn signal bulbs (it's hyperflashing)?
LED bulbs work under a different system than factory standard turn signal bulbs.
With some cars the LED indicator bulbs may not work correctly or Hyperflash.
This is when your new LED indicator lights flashing at a much faster rate than normal.
The cause is due to the lower power consumption of LEDs compared to normal bulbs.
Hyperflashing will cause no damage to your vechicle and not to the LEDs themselves.
This problem can be cured by fitting replacement LED compatible flasher unit or by adding additional load resistors. These parts are available in our online store. Please click HERE

What are load resistors?
This is a widely available aftermarket part for use with LED lights. A load resistor slows down or equalises, the rate at which electricity passes through the circuit thereby eliminating problems such as, hyperflashing or flickering of the LED lights. The load resistors should be wired in parallel with the turn signal bulb. It simulates the electrical load of a standard incandescent bulb.

Another function of load resistors is to eliminate bulb failure error massages when a LED bulb is installed on a vehicle equipped which a CanBus system.
However because load resistors slow down the rate of electricity flow, some heat maybe generated. To prevent any possible problems caused by this heat generation, it is wise to locate the resistor on a metal surface and away from plastic components or wiring.

Does my vehicle need error free LEDs?
If you own a vehicle which CanBus system, it's very likely that you will need error free LED's
As the LED draws far less power than standard filament bulbs, vehicles that use the CanBus system may create a false error massage when LED's are fitted. Error free LED's mimic a standard filament bulb therby not producing an error massage. eg. if a bulbs fails an error massage appears on the dashboard.
And error massage may occur when a standard bulbs is replaced by an LED bulb.

What does the "CANBUS" mean?
This is a standard equipment on many modern cars. It is a computerised system that monitors and checks any faults that may arise, eg. if a bulbs fails an error massage appears on the dashboard.
And error massage may occur when a standard bulbs is replaced by an LED bulb.

Even after installing "error free" LEDs, an error massage can still persist.
This is because some vehicles' ECU's are very sensitive and may require additional load resistors to be fitted together with the new LED bulbs The correct load resistors are available on our website.
