Here is my beauty!

For the lighting I have a 12v 35w MR11 spot halogen powered by a 14.4 v battery. It gives me about 1.5 hour light time and puts out something like 1200+ lumens, about as much as a car high beam. To extend battery life I can also use a 20w bulb which is also plenty bright.

The hard case I have in the back I got of Amazon is make by Swagman. It holds 1,650 cubic inches, that's about 2.5x more than the typical flimsy fabric rack bag.

If you have any question about the conversion or accessories just let me know.
