LED lamp instead of the H1 in the headlamp

Hello tomorrow I get my new moped, the CB 125F. The headlight has only a 35 watt H1 lamp. I have read a lot about it and everyone wrote that the lighting is quite bad / dark. But for stronger lamps the alternator is not enough. Now I have at home already switched to LED lighting everywhere, because per watt power consumption the light yield is higher than with other illuminants. There is meanwhile also as replacement for halogen lamps in the car suitable LED’s. P Hillip’s Luxeon 25 Watt for H1 is supposed to be, just, I can’t find it anywhere. I didn’t find these lamps on Phillips’ homepage and I didn’t find them anywhere else in the WWW. Does any of you have a source? Greetings Uwe
