This is a 7″ school bus tail light full assembly. It is definitely not vintage, but if you have a late 1950s to 1970s travel trailer that does not have taillights and you need something that is the same diameter as the taillights of that era, this is a functional replacement that will give you stop/turn/tail functions.
If you have vintage Auto-Lamp 575 lenses, these are very similar diameter but the base is not compatible with the old lenses.
The base surface mounts to your trailer with four screws on a 6.25″ bolt circle.
It has one incandescent two-function 1157 bulb. There are three wires coming out of the back.
- The red wire goes to the brighter filament.
- The black wire goes to the dimmer filament.
- The white wire is common ground.
The red acrylic lens attaches to the lamp base with 4 screws It requires a 1″ diameter hole 1″ deep in the center for the bulb socket and pigtail.
The heavy duty steel base is painted with black epoxy for rust prevention.
