Correct application Guide Multibeam Headlight

Any idea what these were used on. They have been converted to sealed beams, but originally had three different bulbs: parking, low, high beam. Thanks.

Guide Multibeam didn't have 3 bulbs exactly, it had 3 beams. Make that four if you count the internal parking light that yours apparently had. Most and probably all of them used the American Prefocus bulbs that were common at the time, 2320, 2330. 2530, etc. On yours, there would have been an additional parking light bulb up high in the reflector.

 

The lenses are different right to left and the cutoff is vertical. They are aimed crosseyed. When you beam down with a footswitch, the passenger side bulb beams down.

 

GM cars except Chevrolet used them in the mid 30s. So did some independents I think. I would have guessed Cadillac, but I don't think they had that rib on top. I'd start looking at pics of cars from around 1934-36. The internal parking light is a small clue (suggests later). The fact that they mount at the bottom is another small clue (suggests earlier). Multibeam was around in some form or another for most of the 1930s.

Mounting and wire connectors look like Diamond T truck. They used Guide lights.
