water proof plugs

[StirCrazy]

ok I have been looking for some sort of plug to make a quick disconect for my lights but I haven't been able to find anything proper (Victoria sucks for selection) but what I was wondering is if a 4 prong trailer plug would work? I saw some that have a rubber suround that would seal them when they are plugged in.
or does some one know of something that is made for this that is easy to get.
