fast turn signal

Post by nathan@el » Sun Sep 23, 2012 7:23 pm

Quick question: What could cause one (the left) turn signal to blink at double-speed, aside from a bulb failure? I've checked the bulbs and the fuse, and they seem fine (and both the front and rear signal actually light up, just very quickly). The only time I've encountered this in the past is of course when you have a bulb failure.

It may be a ground issue. Clean the sockets REALLY well in both your front and rear bulb housings.

If that doesn't fix it, change the bulbs so that they are all the same manufacture. Occasionally, one stupid bulb will be more efficient than its companion and it fakes the relay which relies on amperage to set its make/break speed.
