I hope this hasn't already been posted. I thought it was good information.

What I have been using for the last few years. Think I only had one to fail. These are 80/100 & bright is VERY bright. Don't have running lights & travel at night as I work nights & need the light. Told I couldn't use this as it would get too hot & melt my plug. It does get hot & only hint of heat damage, so far, is the boot that goes around the bulb, is a little discolored, but not melted & a lot of miles on it. Only use the bright on the interstate & pisses a lot of truckers off but I am able to see way ahead of me for all kinds on night critters, deer, raccoon, opossum, skunk, armadillos, whatever. And for less than $12 bucks, I will keep using them.

Ride Safe,

I ran a 100/80 on my '87 Sloptail for several years. Did fine in the original headlight bucket, but when I dumped the FLST cowling/headlight and went to a smaller 5-1/4" bucket, the plastic lampholder melted, shorted the hot wires to the ground wire, and because the (probably original) circuit breaker failed, it fried my regulator and stator. When I replaced the charging system I replaced the plastic lampholder with the ceramic type as per the article. Since then the only gripe is that they do tend to burn out faster, and most times I've had the first element fry, drop into the lower element and take it out, too. Not a good thing to go dark on the in-the-woods roads around my neck. It would be nice if they would support the elements better, similar to how rugged duty incandescents are made.

 

I've read that they burn out faster because the cheaper ones are actually lower voltage bulbs "overdriven" to 12 volts to make them brighter.
