Drum Tail Light

[Ford1930]

I would like to see an "explosion" drawing of the Drum Tail Light.
When I press the brake pedal the left brake light works. The right one does not work. In stead the right light (below in the drum) works.
What can be the problem?

What do you mean by light below the drum ?

Do the tail lights work correctly ?

Sounds like the wires on the right taillight need to be switched around.

Yep, thats what it sounds like. A simple wiring or ground issue.

Bring a known good ground to the light case and the socket

I made pictures of the drum tail lights when the Brake Pedal is depressed.
The Left Brake Light "burns". The Right Brake light is OFF. Instead the Right Taillight "burns" weakly. What may be the cause?

Most likely a bad ground.

Sounds and looks like you have the brake light and tail light wires crossed for the right tail light. To verify turn on the headlights and then check the tail lights if the left lower light burns this is correct. However, if the right top light (brake) burns then the wires to the right light are absolutely hooked up incorrectly. Also note the brake light and tail light bulbs are not the same size i.e., brake light 21 cp tail light 3cp. The lower tail light being 3 cp will burn much dimmer than the brake light 21 cp.

Yep, what Frank said.

The top [ higher candlepower] bulb is brake [and turn light]
The bottom [ lower candle power] bulb is tail light

Wires look crossed, easy fix

As advised I made a temporary ground wire. It works. The problem is a bad ground on the right drum tail light!

Thank You ALL for the HELP!
