Tail light issues 72 dodge

[Johnnyd111]

Strange but upon inspection my brake lights don't work, so I open them up. My passenger side rear has 1 bulb. But my drivers side has 2. Any ideas? My assumption would be that they would have 2 bulbs?

The first thing I would do is check the truck/car. With a straight test light check the 3 and 9 pins on the picture below.


If they are working then it is the trailer and if not it is the truck. Fuses are under the hood.

The extra bulb is the license plate/tag light.

Show us the other side too.

Typical setup for most 70's era campers is 2 bulbs each side. One bulb is a combination stop-turn / tail and the 2nd bulb is backup light. You situation may be by original design or a PO modified it but elminated the backup light.

My pop-up is like this. Driver side has two and passenger side has one. The Driver side houses the license plate and the 2nd bulb is for that. I thought in 72 the reverse lights had it's own housing. @ least my 73 does as well as a few others I've seen in that time period...
