Very beautiful appearance and easy to install. However, there are no instructions for sealing or impregnating in the instructions. I noticed that there is a groove/notch on the outer plastic ring/ring so I added silicone sealant to seal it better against the RV wall. The original mount had a thick layer of butyl rubber/sealant between the RV wall and the mount and a gasket behind the lens which this mount does not appear to require. Clever design, the 4 very small screws that hold the lens to the base and have to be removed to change the bulb are too small to be practical and only one of the 3 different small Phillips screwdrivers I had was able to turn them . Don't expect to have to remove and replace them when you need a bulb change (and what a screwdriver really works!). As much as Starlights is promoting LED bulbs, why not just identify which LED bulb the Auto 1156 directly replaces? But I will be buying another one to replace another rusty/yellowed alarm on my van.
