They are CG approved and the bulbs are non-replaceable in sealed units. The lights work great, as you would expect. They both mount the same way, and I don't like the mount.

The mount is a two-hole arrangement, with one hole seating a post to prevent rotation, and the other hole seating an expanding stud that relies on the plastic mounting stud expanding like a drywall fastener when an internal screw is driven in, with the expansion holding it so it can't come out. These expanding plastic studs are delicate.
