What should we do if the LED turn signal of the headlights or taillights flashes fast and the car dashboard function alarms?

We can prioritize the following methods to check the problem of car LED turn signals.

·Step 1: We can turn on the dual flash function to check whether it is working correctly. If not, then it may be that the car’s battery is under voltage(voltage is unstable), resulting in insufficient car power. At this time, it is necessary to increase the capacitance of the car at the corresponding position (680UF, 1000UF, 3300UF).

·Step 2: If the car’s double flash is normal, we can turn on the unilateral turn signal to check whether it’s working properly. If the unilateral turn signal flashes fast, then there is a problem with the lamp power. In this case, you need to use a 12V7.5Ω golden dummy load to increase the power and reach the actual wattage.

We can tell the details to the customer service of Vland car lamp store. The customer service staff will determine what specifications of capacitors or golden dummy loads need to be used.
