Where is the fuse on a tail light?
In most cases the fuse would be upstream of the tail-light switch, so if you placed a test light on the fuse and the chassis, it would light up when the tail light circuit was powered up (irrespective of whether the tail lights were on or not).
What should all fuses make test light?
If the ignition switch is ON but the engine is not running, all the fuses should read about 12V or the test light should glow. The switch to turn things on is downstream of the battery and the fuse. Tail lights should be connected around the ignition switch directly to the battery so they can be turned on without the ignition being on.
What happens if you don’t have a fuse?
They will light up and function just fine without a fuse. Your switches will also function just fine without a fuse. That being said, it is best practice to install a fuse on your circuit. The fuse will protect your wiring in case of a short circuit. If you don’t have a fuse, and there’s a short, your wiring could melt and cause a fire.
What happens when your tail lights are not working?
When the tail lights fail or do not function properly the car becomes a danger or hazard to self and others on the road. You may receive a ticket or citation from the traffic police. Blow fuse – The first thing the mechanics check is the fuse corresponding to the rear lights.

Can a fuse be removed if there is no power?
If you use an ohmmeter, you can get false readings if there is any power in the circuit. In other words, only use an ohmmeter if there is no power on anywhere. You can remove the fuse and then check it with the ohmmeter. It depends on where the fuse is located in the circuit.
