At Sun-N-Fun, I also made some lighting decisions. I purchased LED position lights (bulbs) from PSA Enterprises, then went to the Fly Mart and picked up some good used Grimes lights to house them in.
The gentlemen at PSA recommended I use the Whelen LED landing lights, as they were brighter than the ones he sold. I purchased two of those and also bought two Grimes Landing light assemblies (housing) at the Fly Mart.
I intend to purchase LED strobes from PSA as soon as they are available.
