My 05 bike keeps popping turn signal bulbs in the rear. I found that the lenses were actually bubbling from the heat since they are used as brake lights as well. All is in working order.... just too much heat inside the bullet light housing. I put in a set of cheap LED replacement bulbs and they work OK but these are much bigger and brighter and will fit in the stock housing. I ordered some today so I will post as soon as I know more. Look like they should do the job though.
