I can't work out these lights, there is only one power connection that goes onto existing connections at the headlamp, so the whole lot is running from one power source. I can't see that being a problem, but the headlamp monitor will be bollocksed for the headlamp that isn't giving power to the set?
It has a box of tricks that needs battery power too, what the hell is it? I might knock this idea on the head.
