I have an electric-eye sensored light on my front lawn. Over the past several months, it's tended to remain on well after the neighbors' lights have gone out, then in the evening come on an hour or so before anyone else's.
To me, it looks like the electric eye is clouded over. Never paid much attention to that before, so maybe it always looked like that. But it's REALLY cloudy now.
It's winter where I live, so working with the light probably isn't in the equation soon (the light is either in deep snow, or when thawing like we have now, a lot of mud, and cold weather too). But how easy is it to replace just the electric eye and not the post or the light itself?
The light is nothing elaborate or special - just something I picked up from Home Depot. On the other hand, my handyman abilities peak at or slightly above changing a light bulb, so this is a nontrivial task for me.
