c) front spotlight ( only one) and it won't to more than 30 miles before going dimmer than a dim thing!
Just to dispel a possible missunderstanding, neither the Wassel DC or Varitronic setups generate enough amps to power a spot light for very long. Quite how long will depend on the size of the battery and the wattage of the spot lamp. I have a 7.2 amp per hour battery and I know I have to 'manage' the consumption (I have 2 35 watt hologes so approx 30 mins too). Riding at say 40-50 mph the stator will be chucking out enough to power the headlamp so the battery will slowly drain with the spot on. I have mine wired to only work with full beam and can be switched off when not needed, I have a 55/60 watt H4 Xenon headlamp fitted which is more than adequate on dark lanes but the spots are great for the twisty bits. I seldom need them on for more than a few minutes at a time and if I find the battery going flat, I put it on charge at home. My spots have H3 lamps and I bought some LED H3 lamps which would be fine if they were just for show but the light was far too scattered and of no use for what I wanted. Shame as they took next to current at all
