Jake, if you go back in this thread, I included a copy of the owners manual page that shows most of the bulb specs so you should find it there. Keep in mind that the lowbeam specified is incorrect! it's actually an HB3
Matt, glad that you saw that. It would have sucked to get it all done and not be happy because of the lower output....you got some nice bulbs and at very good price! I think that you'll love them! Just be careful sliding the nacelles forward....the outsides like to be pulled forward a little ahead of the insides. At least on my truck it seemed that way. You may have to reach up under the truck to remove the plastic flat piece that slide over the pins. They come right off and I didn't bother to replace them when I was done...that was 2,000 miles ago now!
I don't know if I mentioned it but I have factory HIDS on my car and these are every bit as good. Now I'm thinking of doing the high beams because I really don't like Halogen bulbs. Way too much energy is converted to heat instead of light so I may change them one of these days.
jered--I've never heard of LED's fading over time. Fluorescents do, but not LED's from what I know. LED's will also last a VERY long time compared to every other light solution out there!
