this is a c5 that was bought form a insurance auction. none of the rear tail lights work what so ever, and two of them have this strange mod. they drilled a hole in the tail light then wired in some different bulb. anyone know what kind of bulb/mod this is?

Its a strobe light. Just like they do on police cars. Lots of people do that on show cars.

ooo Thanks! is there supposed to be some switch for them?

Bill Curlee

SOMEWHERE!

You also have a strobe module SOMEWHERE. Dont use them on public streets or highways. That gets police officer attention REALLY QUICK!

anyone have any idea why the rear lights dont work? except the little middle brake light? also back up lights dont work when in reverse, but do flash when i lock the car with the key fob.

any help appreciated

also car was hit on passenger side by the pcm. but from what i can tell wires are ok.

Bill Curlee

The reverse switch on the transmission (passengers side MN6/12) is bad. Very common issue and easy to fix. About $12. as I remember.

Cycle the emergency flasher a dozen or so times and if that doesn't work, the steering column multifunction switch is most likely bad.

bulbs? fuses? grounds? wiring? start checking everything related to them

wesz0691

all the blubs are fine, fuses are good, grounds are good, the turn signals on the quarters and the tail lights are not getting power.

now after rear bumper cover was removed "service active handling" comes up on DIC.

That is a strobe bulb...wires should run to a power supply and there should be a switch to turn them on somewhere inside

wesz0691

yea, found the switch but it was disconected and i dont see where it connects too. not to worried about it, removing them anyway. now, just trying to figure out why i have no brake lights or turn signals or hazards. mabe hazard switch? idk.....
