Islewis-RCU on my A-26 I have one of those Gem 2000 battery testers and use it for my lower anti-colision light on the wing tips I used one of those led jogging lights with small wires ran out to the wing tips. Through Radio Shack you can get a high powered led in green for the other sid and use the same lite system just wire in parale. This I did on my A-26. Of course you can kill two birds with one stone and make a connection to hock up to your Gem 2000 and use it as your mavagation lights and also will sure be an easy way to check your batteries ant any angle.
On the jogging light system when I was at Taylor I turned it on and left it on all day and caught everybodys eye. They all kept asking if I left my plane on.
