The lights come standard with universal feet mounts, though even with covers, they won't be legal to run on public roads. As far as use as reverse lights with a lens, it depends on how much light you think you need, what you're using the lights for, and how dark your tint is. If they're solely being used as a general-purpose auxiliary light, then they should be fine even with additional lens covers, but if you need distance beyond a couple of yards, then you'd likely be better with a different optic or using one of Rigid's lights that have amber LEDs.
