With all these new vehicles coming out with those effing high intensity crystal white lamps blinding you even on their low beams, I'm tempted to throw a gang of 150W off road lamps on a light bar on the roof and blind them to death.
The new Ford 150/250 4x4's are the worst. I can't believe they are legal.
Put a set of HID's in my '65 using Hella bulb bases. They're great. The ballasts are hidden out of the way but easily accessed and use CAN-bus waterproof connectors throughout. Aiming can not be done with a machine because the housings are flat faced and don't have the nibs on them to mount the aiming tool, so you'll have to find a flat surface about 30 feet from a wall. The verticle cut-off is about 32 inches so they don't blind oncoming drivers, high beam will light up the moon.
