Why My LED Headlight Bulbs Flicker or My Dashboard Report An Error?

headlight bulbsGenerally, headlight bulbs in most vehicles can be directly replaced with LED headlight bulbs. However, some vehicles are equipped with the Canbus system, which controls the whole micro-controllers and devices communications with each other. The Canbus system connects every electronic equipment in the vehicles. Thus, once you replace any one part of them, the dashboard will report an error. As for replacing the headlight bulbs, flickering also is one of the problems caused by the Canbus system. To solve the Canbus problem, you can add a pair of CANBUS DRIVERS to keep the LED headlight bulbs operate in the normal way with reporting errors. So another problem exists;

Is My Car equipped with Canbus System?

After you have installed your LED headlight bulbs in the headlight assembly, if the vehicle still warns you that there is a bulb out, that means your car is equipped with Canbus System.  For example, remove a rear parking light. Please pay attention, it that one cannot be a brake light or turn signal. Drive the vehicle around during the day with the parking lights on. If the vehicle gives the bulb out warning on the dashboard, your car is equipped with Canbus System. If there is no warning, so your car is not equipped with the Canbus System.

The fan is very important to dissipate heat. Most bulbs stop working because of the fan is broken. Heat is the fatal cause of the headlight bulbs broken. If the headlight bulbs have the perfect cooling system, the LED headlight bulbs can work longer. In the market, there are three main cooling system: cooling fan, aluminum housing, and copper wire. Also, some LED headlight bulbs like Auxbeam T1 series and the new arrival A2 series are temperature control, which can directly adjust the beam due to the heat generated by the headlight bulbs, which can effectively reduce the flickering problem.

When the headlight bulbs turn off, the headlight bulbs will still flicker. Due to electric current didn’t completely consumption while your turn off the bulbs. So that comes with flickering or light stay on 20-30 seconds. You can parallel to a resistor in 100Ω to solve this issue.
