Do you have any mounting holes etc from old lights, if so that may limit your choices if you don't want to do any body work.
What about those stainless button head bolts with leds in them - Lite N Boltz. Very discrete, not technically compliant, but they work well.

Or dome style lights, I have some here you can have as I'm sure I owe you a favour somewhere.
Or you could just run the small black Narva L1510 ADR compliant. Depends on the look you are going for. I have attached some photos of John's RCR-40 with them on. I have larger versions of the photos in my gallery you can zoom in on.
