Just played this game. I wanted to stay away from LED's at this point, as the cheaper ones technically aren't road legal. I went with a set of Hella H4's (which I guess are also not technically road legal, but not as blinding to oncoming traffic). Building your own harness is really easy, using two relays, and taking power off the battery, versus running it through the switch. Switch is used to initiate the relays. There is a harness available from LMC truck, or get on youtube, couple of how-to videos for our trucks. The big issue is running higher amperage through the stock switch, it just doesn't take it well. I like the cut of the Hella lights, gives a nice crisp beam. They can be had for around 100.00, or watch ebay. I found mine NOS for 35.00. I ran the 55/60 watt bulbs, and it is a vast improvement over sealed beams. You can step up to 100 watt if you want flamethrowers.
