Thats basically the route I'm going, switch as much gear to 12v as I can so I eleiminate extra wiring and complexity and have the ability to use it while traveling.

There are plenty of automotive lights tht work just fine and can be bought cheaply in parts stores, junk yards, catlogs, etc and then you can swap the bulbs for led's if you want.

There are whole catalogs such as http://www.truck-lite.com/wcsstore/tl/splash.html (napa stores can order those in for you)
