Mine must be special cause I don't get alot of vibration even at 10K.
I also fixed my headlight and I cannot remember the bulb number. Mine was blown so I took a dremel and cut the old bulb out, had to break it to get it all the way out. Then I JB welded in I think an H4 and kooked it straight up. Lots of light but it pulls a few amps, slows down the blinkers and dash lights.
