All my lights will come on by them self even just sitting in driveway over night. Lights work fine when I use them but sometimes won't shut off by switch. Where to start? 2000 Freightliner FLD Day Cab.

Do you have a remote that opens your door locks and a alarm? Check the battery in that cursed thing.

Then if you in a area that you run into that mag chloride it has very corrosive problems on wires and electrical units.

First thing that comes to my mind is the relay is sticking closed.
Second thing is your switch could be sticking closed.
Third thing that comes to mind is the light circuit has a short to power somewhere.BoxCarKidd Thanks this. -

Under 10 bucks for the toggle switch. Start there.

Of you can access the guts of the switches and they are mechanical with contacts, some Caig DeOxit sprayed in the switches might resolve the issue. Use when depowered and work the switches back and forth to clean the contacts in the DeOxit. $15 for a small can but very little needed, set the nozzle to the slowest setting and the can will last.
Also, they make battery cutoff switches, even remote ones. Might be handy even if you resolve this issue.
