i recently bought a new set of taillights for my car...installed htem with no problem except for some lil circuit box. well not when i press on the brakes whether or not the ignition is on or key is in the ignition, if i press on the brakes my parking lights and my brake lights along with the lights to my speedometer lights up....anyone have a clue?

 

I know how to fix that

 

what would that be? it seeemed to be a bad light...i removed the replacement bulb and it didnt do it anymore

 

You need to elaborate more on that or else we wouldn't need a msg board.



Were you able to use another bulb with no problem?

Did you change the complete tail light housing or just the bulbs?
