I just bought and received my W650D lights and, while the wireless idea is a good idea, wanted to know about wiring them to a switch. Reason being, I am not keen about carryng around a spare battery or the possibility of losing the remote. So, I sent an email to Warn and just got this reply:
You can wire the lights to a hard wired switch. I believe we will have a kit to do this some time in the next couple of months.

I think I will install them up now, and get the kit when it is available unless anyone has any other options.
