My 3rd tail light is constantly on when lights are turned on is this correct or is it meant to be a break light
It should be on like a running light when the rest are on, and should get brighter like a brake light when the brake pedal is pressed. A 3rd brake light is actually mandatory by federal law from what I’ve read. Does it act like a brake light when you hit the pedal? And a running light when you aren’t?
