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?
