I was originally going to mount the switches for the lights to the side of the ignition key, under the guage panel, but it seems like JD made that panel almost impossible to remove. I actually prefer where I ended up mounting them under the drivers seat. There are two switches, one for each light plus a panel mount fuse holder. I got high current switches, and skipped the relays. The switches are splashproof, and also protected by rubber boots.
