When will you need a decoder?
When you install LED headlights into your car and have any of the following problems, you may need a decoder.
- Bulb flashing when turned on.
- Headlight error displayed.
- Bulbs stay illuminated after they are turned off.
- Abnormally dim light output.
Functions:
- Solve the demand of power problem
CANBUS system monitor the current in-rush of the light bulb it's controlling and when it sees a larger amount of current, or a smaller amount of current, than the original bulb it causes a problem. It uses capacitance to smooth out the power demands of the new bulb and helps the system adjust to the aftermarket product.
- Fit to pulse power supplied cars
Pulse width modulation, PWM, is a technology to reduce the heat value of halogen bulbs, help the bulbs last longer, and save more power while operating. Installing LED headlights into a vehicle with PWM configurations will result in flashing bulbs or bulbs that turn off after a few minutes. The PWM module's large capacitance will basically store up power to eliminate the pulse and supply to the LED headlights with a constant current.
- Solve the DRL flicker problem
The idea behind the DRL is a safety feature for daytime driving. It does this by dimming the original halogen bulbs in a few different methods:
- Dimming by resistance.
- Dimming by PWM.
- Dimming by voltage reduction.
