You can take the switch off the light bar and use it. Just put a rubber plug into the hole that's left behind. Buy a rubber switch boot (a buck or so)at a local marine or heavy equipment supply store and install it on the left side of the console. You will have to drill the hole out just a little bit to make it fit. I wired the switch off the high beam indicator so the lightbar only comes on with the highbeams. Since it's always on with the highbeams I didn't worry about a separate indicator. Plus it's right there on the console so it's easy to see.
