third brake light not working properly

Postby siegele [OP] » Dec 16 2011, 5:07am

i bought an aftermarket led third brake light for my truck but it only works when the interior lights are on and the cargo lights on it never shut off unless you turn the cargo light switch on the dash off. anyone else has this problem or any suggestions? thanks.

I think you have it wired wrong. Sounds like you have it tied into the cargo lamp circuit instead of the brake light circuit.

The cargo light works that way, even on stock. Push the button, lights come on. Push again, lights go off.

Now, the brake lights not working right is an issue. What company made it?

Is it a cheap aftermarket light?
