Question Weird problem with LED taillights

Hi everybody,
here's my problem.
I made a change to the LED taillights to get the same result of you guys (full led lights when turn on the light switch in first position).

Like this :


But when I turned off the engine and restart it, it's the black out... no lighting...
I don't know why

I'm going to reset the ECU this night but it's very weird...

Thanks,
Denis.

Did the light come on at any point? Don't quite understand if it worked, then did not work, or it just sometimes works ...

It works once and after nothing. To get it back on again I need check all the connections. It works until next engine start...

Thanks,
Denis.

Sounds like your overloading something and it resets when you sut it off. Did you put resistors to keep the load stable.

No resistor installed.

I agree with you Candyapple but which resistor installed and where?

Thanks for your help I appreciate it
Denis.

Resistors are typically used to trick the light sensor into thinking there's a higher draw then the leds have. Interesting to see others thoughts and experiences if this has happened before.

I have disconnected the upper leds and now it's fine.
I'm going to find the right resistor to light again these leds.

Thanks,
Denis.
