Hello, I have a whole bunch of stuff here for a GoPro. It's all I used for scuba diving for up close macro photography. The lights work, the tray is still sold from beneaththesurface1 dot com. The lights are Aqualite eLED Pro and the lenses are from Backscatter. It's a pretty cool set up if you need lights and a good way to mount them. I would prefer to sell it all together, that's why the price is low.
