Look around at the LED lights, They have their own brand which are excellent. Also, Whelen TIR3's are awesome little lights as well., They just require a Power Source, Ground, and then run them to a Momentary switch. I have 4 of them for my Grille (2 White, 2 Amber) and will sync them together (Which they also have a wire to link to each other).
Each light has 12-20 Patterns when not synced together, and 12 #2 Synced patterns. Make sure you do your research and know exactly what you want. BTW, Don't get any lights that may be Illegal to use in your State. (EX- NC, does't allow use of Red, or Blue lights except when given permission or for certain vehicle's.)
Hope this helps...
