I replaced mine with some brighter set from Autozone that were listed in the catalog, I think. I can't tell you what since my truck and I are separated by about 3,000 miles. They were a bit brighter, but I had already lost one in a much shorter time than the OEM bulbs. been considering what to do in terms of replacement, but since I'm not around with it, I haven't done anything.
I think... Sylvianna X3 or something?
