I have a OMM red rocks rear and I mounted a basic Trek LED blinkie to it. I bet I could mount a bunch of different ones, you just need to find the right kind of light. What I did with mine is simply buy an angle bracket, basically it's an "L" shaped piece of aluminum with two holes drilled out. I used a nut and bolt to mount the L bracket to my rear rack's top shelf. You have to mount it such that the the hole in the bracket is perpendicular to the bike's lengh....hmmmm... basically the screw hole would face the side of the bike, not the front/back..
Now, you will need to find any LED that mounts to the seatpost using a nut and bolt. Many of them will have a collar to go around the seatpost and then have a arm with a hole in it and a notched washer (for the angle) and then you use a nut and bolt to mount the LED to the collar, adjust the angle and tighten. Do you see where I'm getting at?
Now, if you have the right angle bracket and right kind of LED, you can simply replace the bolt and nut with one that is long enough to work with your L bracket. Thread the bolt through the LED, then through the L bracket and tighten the nut after you adjust the angle. Use threadlocker if you need to...
Best bet it to buy the L bracket at a hardware store and bring it with you to the bike store and kindly ask if you can try it out and see if it works. Worst case scenario... get a drill with a good metal drill bit and cut your own hole from a L bracket without holes or with one only.
It works great for me. On my red rocks rack, I have my Trek LED on top and then using the same bolt that I have for the L bracket, I used another L bracket below the top shelf and I mounted a basic passive red reflector below. And then I have an LED on my seatpost as usual.
