They are beautiful, but as an electronics person, I realized that they are not waterproof and it's not easy to screw them in since the threading is not secured to the body in any way! I bought liquid and gel super glue to tighten them so they can be screwed in! Then, the small circuit board for connecting the wires was not insulated, and by chance, it wasn't touching the bare aluminum of the body, which would have caused a short circuit if I had simply installed them without fixing them! Also, I should mention that one pair, I don't know why, while during the test I did both before and after sealing, they lit up, but after being installed in their place, they worked for one day and then nothing!
