turn signal flashes rapidly

[crioten]

i dont know if anyone else has had this problem, but about 6 months ago i swapped out my front turn signals as well as my sidemarkers (for the clear benz ones) and ever since then the right one would sometimes freak out and blink really fast, and the left one would stay the same. so now im bored and im trying to figure this one out...

at first i thought it was the headlights turning on that would do it (thats what caused it to do it at first), but now it does it intermittenly(sp?) so now im confused...

i think it could be:

1) a bad ground wire somewhere (because i swapped out my sidemarkers for the benz ones at the same time)?

2) or could there be a wattage/amperage(sp?) problem with one of the bulbs in either the turnsignal or sidemarker lights?

what do you all think?

thanks
