Light good, but base sucks.
I like the bulb section. It’s sealed perfectly. The base, not so much. The mounting hole have brass inserts that are large, but there is still not able it 2mm of head room for the light. One of these screws is the electrical ground for the bulb. Water can get in around the base also as there are four slots where it contacts the vehicle. I suppose this can be sealed with RTV.
