Ok so i hooked my fog lights up to a switch that i mounted in the compartment in between the seats, I also hooked up a small blue LED just for fun so i know if there on or off. but when i have them on for like an hour the switch is really really hot. the switch is all metal.

Is it normal for it to be like that?

sorry if this is a stupid question I'm still kinda learning by teaching it to myself pretty much.

No. Slightly warm maybe, if you take the main power through the switch (i.e., don't use a relay), but nothing that could be fairly described as "really, really hot".

Possible reasons:
1: Bad connection to the switch.
2: Switch not rated for the current.
3: Switch gone bad (corroded contacts or similar).
4: Too narrow wires (this one will actually mean that it is the wires that grow hot, but in extreme cases they might warm up the switch also.

I would recommend using a relay if you are not doing so already, particularly if you are running multiple or extra bright lights. Use fairly heavy wires from battery to relay, relay to lights and lights to ground. The wiring to the switch and the switch itself can then be light duty.

If you are already using a relay, I would say that your problem is almost certainly a bad connection or a bad switch.
