Help please

So I have an aftermarket camera that has been mounted onto my number plate light (which the light is now not working) surely I wouldn’t need a whole new casing for the light to work?
I’ve tried taking the casing off to see but the screws are so badly rusted I’m not sure if it will come off, just thought I’d ask here before doing anything else

I'd hit it with some penetrant spray to loosen the screws. If the light is out, you probably just need a new bulb. LED bulbs are cooler and don't heat up the plastic like regular bulbs can.
If you can find replacement screws, get something stainless that won't rust.
