Hi all.

When I first got my 1988 300SEL, the left front turn signal bulb was blown, which was setting off the blown bulb warning lamp on the instrument panel and I was getting the fast blinking on the right side.

I replaced the bulb and all seems fine, but I still get an occasional warning of a blown bulb and the fast blinking, BUT this time, BOTH front and rear signal are working. Whats strange is it will blink normal for about 5 times, then flash fast for about 10, then slow for a few times, then fast, etc? The bulbs are tight and the connections seem fine, because the lights are working. The left side works perfectly.

Does anyone have any clue as to whats going on? Faulty sensor or flasher?

Thanks!
