I have the weirdest problem, my left blinker sometimes works fine, and others blinks fast and the back signal doesn't light up. When it happens I can usually just turn the signal off and then back on again and it works fine. Don't think it can be the bulb and it looks fine. Any ideas?

Try replacing the rear bulb. It sounds like it may have an intermittent open in the filament that will sometimes close and let the bulb work. Other times it is open and won't work.

I have seen this problem with both bulbs and fuses. :eek: BOY!!! If THAT wasn't frustrating!

X2---- Had the same problem with a bulb on my 5th wheel. At first thought it was the socket, because the bulb looked good, but while tapping on the bulb when it should have been on and wasn't, I saw a small spark inside near where the firmament ties to the supports. Replaced the bulb and no more problem!

Thanks, I'll get a new bulb, I just thought a bulb was either good or bad, guess it can be both.
