Thanks for the responses guys. I thought about the extendable ones, but I haven't seen any that were led. I am running ALL led lights on the boat with the exception of probably a spotlight (I already have my led navigation lights and red courtesy lights). I will just end up using one of the plug in sockets and pull the light when not in use. I will probably go with the 48" to get it fairly high overhead. I don't want to run into any issues with it blinding me while night fishing. I AM considering installing a bimini top eventually Bob, but I wouldn't have a need for it to be up at the same time that I would need an anchor light out. If it ever became an issue, I could always buy a really cheap, shorter light for those instances.
It is my opinion that having the anchor light right above you will hamper your vision while trying to drive at night.
Thought about mounting it on top of the outboard?
