I have just fitted a pair of these
https://www.ebay.co.uk/itm/1pc-White-BA20D-3030-66-LED-Motorbike-Headlight-Bulb-Front-DRL-Light-6V-1000LM-/274542677311?var=&hash=item3fec04cd3f which are
White BA20D 3030 66 LED Motorbike Headlight Bulb Front DRL Light 6V 1000LM #=-l=-to my Aprilia.
The light is not inferior to that of the previous quarz halogen bulbs with a slightly less focussed beam. Dipped beam is dimmed rather than dipped but I doubt it will cause oncoming traffic any problems.
I have also fitted led festoon type sidelights, and stop/tail
1157 P21/5W 380 BAY15D 17smd 5630 CAR STOP TAIL BRAKE Reverse LED BULBS AC 6V which are better than the tungsten filament ones.
The current drawn is minimal such that I can use dipped headlights in the daytime with no concerns about load on the dynamo.
It is important to get the polarity right of course and it took a buit of fiddling about to get everything to work properly but wirth the effort.
Not particularly cheap even from China but cheaper than buyng them from the UK.
