Thinking of switching them over to my lowbeams and replacing the silver stars since they die out all the time. (the 9005 conversion).
I purchased the Ultra'* and they seem to be doing fine, but sylvania has a reputation of dying out. Depending on which member you ask, i know theres 1000000000 posts on silverstars but nothing showed up on the Hella'*.

Thanks all.

i have hellas in my p/a. been there since 04. i have the 80w 9006s, and 100w 9005s. the only thing i did to the harness was that i used di-electric grease, but you should use that anyway.
