I'm looking for the best bulb choices for a bone stock 2004 Chevrolet Silverado half ton, 4X4 Z71 with good,clear oem housings. My son's truck, a hard working kid who drives long distances at night, wanting to get him the best possible night vision. I'll "assume" that the same bulbs would be best for my Wife/Chics '03 GMC Yukon XL? Thanks, J
