After being told by the police that my slider had to be outside of the no wake zone, i started to worry about boaters running into it after dark. that would not be cool.here is what i am trying. i have been forced to sit in traffic for an extra 1\2 hour every morning on my street because there is road construction that should be done at night but is done during rush hour traffic instead. so they were nice enough to supply these two led lights that turn on automatically when it gets dark. they run off of 4 D batteries. since they are LED's, they shouldn't have to be replaced for a long time. what do you think. Any other creative solutions. pulling them in nightly is a pain in the butt.
