« on: November 16, 2009, 08:02:32 PM »
Well i have put 2 tuen signal switchs in my jeep for this issue, first one lasted 2 weeks, next one lasted like 3-4 months.  Now it is doing it again and i am wondering what keeps causing this issue. Anyone have any ideas??? Thanks

check if you have good ground at the stop lights and headlights - that's the only thing i can think of unless there's some weird wiring issue (some short somewhere). If you did some work on the wiring retrace your steps, you might find the problem there.

I've seen this when the turn signal element burns out and the
remaining chunk falls across the tail light element in the bulb.

Drove me crazy for a couple hours till I tracked it down.

Check you trailer plug... easy to drag and smash a wire.  It can cause all kinds of nasties.
