i noticed today that my brake lights are always on. its a 1990 gti corolla. its a double filament bulb, so when i turn on my lights the brighest filament comes on and stays on, ie the "brake filament"! and when i hit the brake the less bright filament comes on, ie the normal rear light, so there mixed up! anyone got any ideas on what it could be? i fitted a set of hids yesterday, could they be causing some sort of problem?
