OP specified side facing though...

The two outers mounted above the windshield on my DJ point 45 degrees to either side for that same reason, but you get glare putting em up there.
Have you looked at LED lighting? A lot of places have started using the term "rock lights". You can get away with really low wattage using LED and unless you go overboard with em you could probably wire em up without relays even.
