Recently picked up a Fourtrax 300. Works great, good unit.

It has a switch on the light panel that I have no idea what it does. Guy I bought it from had no idea either. If it’s aftermarket, whoever put it on did a good job. I’ve searched pics on the ‘net and I don’t think it’s from the factory, but I might be wrong. Hoping someone here might have a suggestion. I’d rather not take the panel apart to trace the wires if I don’t have to.

Here’s a pic.
