are these what you are looking for?
These are the two adapters I told you about in my previous post -- first pic is the 1M/2FM .... it will fit into the 2nd pic adapter (1FM/AC) and you can attach the AC (alligator clips) to the battery, and have two recepticles for your lights. I use the 1M/2FM adapter to run two blacklights off a portable jumper battery ... or both, to use a marine battery (should I forget to bring the jumper battery ) ...... cp
