Anybody purchased a led rear-light conversion or a plug n play stop-tailight led bulb for an ac system
Its been a long time since I did electronics :bigsm:
But leds only worked correctly with a dc supply and needed the current regulated
Some will work on ac ~ But normally have in-built electronics
Minature bridge rectifiers and voltage/current regulator micro-chips & other trickery bits
Or
Do they just rely on the human eye not noticing the ac fluctuation
The plug n play led bulb I saw advertised stated it had something like a 5000hr life
But if there is no current limitation when the regulator is kicking out over 13volts
They definatley won"t ~ Especially the bright white ones
Somebody please feed my need for useless information
led conversions
the MB rear led works great on AC
Could not settle ~ So i"ve been fettling
Done one for my mates framebreather as the lights r naff
plus put led festoons in his number plate srround
Knocked 2 bridge rectifiers up ~ one for the stoplight the other for the tail-light
Put 2 current regulators in aswell ~ These should fit behind the lighting plate I hpoe
So there will be 6 leds tail-light ~ 9+festoons brake light all dc~ urrent regulated

Just a point My series 1 has a reflector in the middle of the lens and this covers most of the LEDS inside you may find it better to have the leds away from the middle. Mine is a bought rear light useing Red LED's, for a pit bike. It fits inside the original Lens. As the original light had tin foil and wood screws with 2 pitiful festoons I thought it was an improvement, I had to fit a white numberplate light for a keen MOT man (who was only doing his job lol) I am running full DC.
I have fitted one to my GP, think the packet said it was for a series 3 but will fit GP.
did a bit of chopping and messing but finally got it to fit.
12v AC and works a treat, very impressed with it.
No probs with M.O.T.

I was fed up with my headlamp dimming when I operated the rear brake. So tried a LED rear/brake light bulb. Whilst it was OK it wasn't as bright as the old filament bulb. (My Gp is fitted with a SIL electronic ignition with a Ducati regulator) So I've just fitted an LED rear light board from Rich Presley. http://www.richpresley.co.uk/led-rear-l ... -933-p.asp
It took a bit of fettleing, in that it had to be glued into place with silicone sealant. However it's bright, doesn't cause my headlamp to dim and works like it should!
