Stay away from that Ebay crap!!! I have seen bunches of pics of light housings melting from them.
If you want more light you need more power. Go to Gos racing web site and get their upgraded harness with relays for the 9007 bulbs, I am using it and I was amazed at how much brighter the 9007 bulbs got from giving them the power they need. It was such an improvement I never upgraded my bulbs. I did alot of research and the best bulb to use for the 9007 harness is these.
Replacement 9007/HB5 Bulb, 12V, 100/80W Xenon, Hella High Performance
There is a member here named CaryT, and he educated me on lights and he actually sells these for $33 a pair, IIRC. You must be real careful as there are a ton of aftermarket bulbs, many of which can do harm to your truck. Also stay away from the Blue garbage.
The next step up would be upgrading to the 2005+ headlights. I am actually doing this mod tomorrow, the 2005+ headlights use the 9008 bulbs which are brighter, they too will perform much better with the upgraded harness from Gos racing, don't just buy the pigtails to convert the 9007 socket to a 9008, do it right and get the upgraded harness with relays.
