Nice idea and resistant to bolt croppers but worryingly cut in 16s with cable shears on youtube

It would be simpler and safer to take the battery off and charge it in the house (OK I have bikes that are easy to take the battery off,some are a pain)

Half the problem with ZX7R headlights is the underspec'ed 5A wiring to the lights and crap dip switch: On mine I wired up a UK headlamp ( 2x 45W incandescent bulbs ) so that the feed to the lights was all 15A cable straight back to the battery and switched by a relay operated from the dip switch. Now both headlamps are on all the time and now its brighter than Euro spec one incandescent / one halogen projector that it came with. Just bypassing the spindly wiring and switch makes one hell of a difference If you fit higher rated bulbs, they wont fit properly since one tab is slightly different on the 45W bulbs and if you cut it off to make it fit, the 5A wiring will likely overheat and melt the insulation BTW if you have a projector, it will be a euro spec so the beam pattern is the wrong way around which also wont help. IIRC projectors were never a standard fit for UK but there were so many parallel imports they seem to be quite common. Relays and fat cables for the win
