you need to undeerstand that without a switch the neons will come on and stay on the moment the car is switched on.

It should already be fused, but make sure the fuse is rated to handle the demand on the circuit or you'll be replacing fuses all the time.

wat rating fuse should i use im gonna put 5 20cm 12v neons and im putting them in parallel, with a switch in the circuit

the original fuse will be fine but if you really wanted to change it over... 5amps.
