I don't recall the brand. But both the front light and the stern lights are LED... for long battery life, the battery is in an O-ring sealed case, and either unit removes by just pulling a bent clip pin at their base.

I had to glue a base to the bow of the inflatable for the light. The stern light sits on an 18 inch or so PVC tube which is C clamped to the outboard board on my inflatable.

The whole arrangement is pretty sturdy.
