Thinking about replacing my headlight bulb. do I need a anti vibration bulb? Also what is the best bulb to buy?

Make sure you use the same watt as your current bulb. I replaced my stock bulb with a much brighter H4 bulb.

 

I usually try to run IPF or Hella bulbs. They hold up to the vibration well since both companies specialize in off road lighting and they are both brighter than stock.

 

I put the PIAA bulb in mine, money well spent.

 

I put one of those PIAA vibration resistant $60 H4 bulbs in my ’09 Street Bob and first time out in the rain….apparently the extra heat shattered the headlight glass. Only thing I can figure unless I tightened the ring too tight and that helped it along. FYI
