hey guys i just got my windows tinted. they forgot to plug in my brake light on the rear deck so i plugged it in. then i go see if it light up but no. now im wondering if it is only a single stage thing. meaning does it only go on if i press the brakes. so i tested it and yes it only works when i press on the brakes. is it so for everyone? if someone could inform me on the rear deck brake light only works when applying the brake? thanks for the help

 

Yes it's a brake light only, single filament bulb that only lights up when you press the brake.

 

ok thanks for the help
