My right rear taillight lights up when I turn the lights on. No brake light or turn signal though. I already checked for voltage from the power and trip wire or control wire in my car color code for the wires
RR tailight
Before connector
Green/white stripe - turn signal
Black - ground
Green - power
Harness from the plug to the harness attached to the taillight.
Green power
Black negative
White with red stripe I believe trigger for turn signal
Main power and ground were great
Issues again.
No brake light illuminating.
No turn signal only for the right rear.
All fuses are good.
I replaced the bulbs.
The trip wire or turn signal wire did have a lower voltage than the left side but would fluctuate the same I grabbed the highest readings
Left side had 6.2-6.5
White with blue stripe
Right side 4.2-4.5
White with red stripe
Please help
