I've run the Ultralights for about 5 years now. Had good luck with them at first, but lately, the $25 replacement bulbs seem to be OVER sensitive to bumps and stuff.
We run 3 headlights when we frog gig, and almost every trip, I have one that will go out. Bet I've spent $200 in bulbs this year for those lights.
When I first got my AC light from Light Headed, I wasn't real wild about the extra weight. The first night I found myself continuously re-arranging the light, hat on, hat off, hat forward, hat backwards, but there was nothing I could do to make my brain tell my head, it wasn't there.
But after a few trips, the old noggin is getting use to the extra weight, and last night I only found myself adjusting the fit a couple times. Oh, and another one of the Ultralights didn't work last night when I pulled it out of the dry box. Never bumped it on anything either.
Still can't believe their is not a way to change out the $2 lightbulb, instead of having to purchase it assembled with the bowl for $25.
