I bought 35w bulbs off amazon few months ago.
Got 5 Hella bulbs for my Piaa fog lights...the all failed within a month.
Fortunately Amazon has refund policy so I set em back and got my money.
Maybe it the vibration but I seem to go through more bulbs in those lights then I should.
What ever you do, dont run 2x55w bulbs in those or youll be push starting a bike with a dead battery
