LMC sells a kit to upgrade to a better bulb, I don't think that they are HID but they are pretty slick looking. They are clear glass and you can get them in the two sizes of the 60-66 trucks. They might sell them for the other body styles? I want to get a set but I need four bulbs for my 61 and then I would need the headlight wiring beefup kit too. Anyways they look cool and you can even get blue bulbs for them to get that "Xenon" look. Check them out at:
