Chasing an electrical gremlin

[jbgroby]

I hope i explain this correctly and also hope other can direct me to the possible fix?

When I pull the headlight switch out to the first position the hood running light and tail lights come on. When I press the brake pedal the passenger side brightens but NOT the drivers side.

BUT when I pull the switch to out fully to turn on the head lights, the tail light out out?

Any pointers?
21 circuit from E-Z wiring is what is installed

Thanks

I believe the tail light is a two filament bulb -- one being running light and one being brakes. If the drivers side doesn't brighten, it would mean either the filament is bad or there's a bad wire going to that particular filament.

I BELIEVE the front parking lights are supposed to go out when you turn on the headlights -- is it possible you got the front and back parking lights reversed?

The hood lights go out when the headlight come on as they should, no matter the position of the switch, I still have power to the brake switch when I press the brake as I should as well. The dash and front end works as they should, its the brake lights that are making me crazy.

check your
rear bulb I've seen the filaments burn through and fall across to the other filament and back feed

I'll buy two new bulbs and give it a try. Thanks
