. I am writing you because i have a prolem. For one tail light ( outer or inner - is the same) i use 2 led rings. One (red) for gauge and brake light and one for turn signal. The problem is that when i turn on the gauge light it lights only 1-2 seconds and stop( that is always) and the other problem is when the turn signal is blinking and when i push brake the turn signal stops working. I tried with change software ( stop cold check ) -nothing again. When i connect the led rings directly to the battery there is no problem , everything is lighting. Can you help me please, can you give me some advice - how can i make the tail lights work when they are related to the car. My car is Golf 5 (euro)
