When will you need a decoder?
While you install led headlights into your car and meet the problems like the situation below, you may need a decoder.
(1) While you turn on the light after installation, the bulb keep flashing.
(2) Computer shows error of headlights.
(3) The bulb still keep lighting for a while although you have turned off the light.
(4) Lighting is every dimmed, not bright as normal. Functions:
1. Fit to Germany cars which need electronic decoding.
There is a CANBus electronic inspect for the light while you turn on the engine of Germany cars, so it needs electronic decoding. And our decoder can offer this electronic decoding function. For some Germany cars, the system will also check the working power of the headlights bulbs after you turn it on. In this situation, you still need to add a resistor on the headlight bulbs to satisfy the demand of power.
2. Fit to pulse power supplied cars.
Pulse power supplied capacitance is a technology to reduce the heat value of halogen bulbs, make the lifespan be longer, and save more power on working. But led headlights need constant current supplied, not pulse power supplied this kind of intermittent power supply. So while you install the led headlights into the car with pulse power supplied device, the led headlight bulbs will keep flashing or flash and then lights off. In this situation, decoder will be a large capacitance and store up the electric on it and keep supply to the led headlights bulb current constantly. (If meet pulse power supplied problem, you can ask 4S store to revise your car into constant current supply too.)
3. A small electronic component for Toyota cars [Capacitor Decoders] Phenson led headlight decoders are capacitor decoders which transmit by pulse signal, much better than resistance decoder, it is environmental and engery saving;
Kindly Note: If you are not 100% sure it fits on your car, please ask a question for help or contact with us directly and tell us about your car model, we are happy to offer you a solution.
