I found out some more info from their dealer.
It's not all that chea considering some major draw backs of the housing.
If you want a strobe electonic connector put in it add's to the cost and they recommend Inon and make the electronics special for that anopther couple hundred bucks in there.
It has Inon Port Mounts ... and i know nothig about Inon Ports ? anyone care to tell me if that is good or bad ?
