The 40 year old charging system on my bike engined kit car only just copes with ordinary H4 headlights, bearing in mind there was only one headlight on the bike, two on the car.

I’m using headlights more currently (sorry for the pun!) so thinking about fitting LEDs instead. There is no error-finding software...

Two questions: will they take less from the battery/alternator, and will they give as much, if not more, light output?

Thanks in advance.
