there is none, will have to replace lights, should came on with running or parking lights.

The licence plate lights are in the same line as your tail light wiring assembly. I assume your tail lights are working or you would have got a ticket for that. The wire is either cut, broken or unhooked from the tail light wires (which usually are brown). If you can not find the problem, you can always run a new wire to the tail light wire from your licence plate wire. Then they should work.
Your other problem is that the license plate ground is rusty & not grounding, which would also not let them work, so you should probably check that first. Rick

You need to change the bulb there.

there is a short somewhere.put a test light in place of the fuse.
the light will glow bright.when the short is removed,the light will go dim

The license plate light should be on the same circuit with the tail lights.
