These are exactly the same bulbs as the more expensive 6 pack except they are unsealed. Remove the 2 screws from the back and pry off the lens, attach black RTV along the edge of the lens and a string is inserted into the hole, then mount and seal the screw heads and you get the exact same lights that they sell almost twice. so many. If you don't seal them, once they get wet they will rust inside and stop working. The wire is so thin that I strip and double it, then put a drop of solder on it so I can crimp and shrink it. Connection. All in all if you put in some effort they will be a very good light.
