Headlight Adjustment - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I don't remember the last time I drove my truck at night, but I need to do some early evening driving tomorrow.

What's a good procedure to check and adjust the 7" headlights on my 69? The centers of the lights are 28.5" from the floor. Thanks.

Turns out the alignment was just about perfect. Drivers side was a little lower as I guess it's supposed to be. I raised it 1" or less on the wall. If I get flashed I'll drop it back down. Horizontal distance between headlights on the wall looked the same as on the truck, but it's hard to measure.
