Just saw this listed on eBay. I’m sure we’re all familiar with the 7620 and 7622 beacons, and their bigger cousin the 7624. This is a 7633. I was expecting a 3-bulb version (which I’ve never seen before) but it’s 12 volts and it has the same two bulbs as 7622. Does anyone know what different about a 7633?

@Skulldigger found a listing that indicates the difference is in the lens material:

This is a really old post that I found doing a search for Grote. Anyone figure out the difference in a 7622 and 7633? According to this ad it is the makeup of the dome. Acrylic is standard and the 7633 is Polycarbonate.
