LED rear light

[henri]

with the recent weather cancelling outside play ive got on with a little side project , led rear light inserts with a built in ac/dc converter to stop flickering .IMG_2967 by henri briggs, on Flickr   . 
theres a wiring diagram of the circuit , put 6volts ac in an get 8 volts dc out, 12 volts ac in an you get 17 volts dc out . IMG_2966 by henri briggs, on Flickr   .
a little video of it in action , ive used pre-wired led's that come with a inline resistor to protect them from overload/voltage spikes .H

i was just about to post a thread with what led festoon lamps work best with ac output as the vmc stator is a bit lacking it the power department
and a 20w front lamp is a tad to dim for my liking, i was thing capacitors to boost it up a bit
but if such lamps are available for ac i need 2, or is there a ba22 led for the front light that works of ac?

which headset jonny as theres led headlight units for v90 ,primmy/90ss an 50 specials available . made by evok ,an come with a smoothing module same as my above circuit , there about £95 a pop.H

95 quid lol, l
thats a new piston
i have a vma1 headset, which is slightly different to the primmy
id rather the led at the rear and a 25/25 ba22d at the front, maybe hid
im a sparky by trade but electronics aint my field, did get taught all that shit at college, but that lesson was right after lunc so we just stayed in the pub
rather than learn resistor colours and values etc

my college was engineering , an friday afternoon was "fluid dynamics" after we had had a pub lunch, guy had the most boring voice ever .in case ya wondering ,fluid dynamics is mostly how fast fluid with a certain % particulate matter in suspension goes down a pipe . theres variants , pipe size , bends n gradients etc , but basically its "how fast last nights rubys going to be the councils problem now" .i failed that module 1st time round mostly by being asleep thru it .
there is another way tho.
vma1 headsets still 115mm headlight , so cheapy led spot from ebay , an a bit of fettling , an a doohickey like above an roberts ya fathers brother . more in morning , past beer oclock here . an i'm a tiredy boy , cabled n loomed up , forks n engine in a v90 today , an my backs screaming .H

i feel you brother as my back is fucked too, its why i had to stop work, working on scooters
is a painfull task, i just turn mune upside down to do the cables with cut down half spanners
