My buddy has just fitted an LED headlamp bulb and cant praise its brightness enough. He had a prefocus bulb in before. Instead of 5A draw, from my fitted halogen P43t 60/55w, the LED claims to only draw 2A. With this in mind, could I fit a smaller, less AH battery?

LED headlamp bulbs are illegal here in the UK, it seems to me that people expect to see bright headlamps nowadays. I have a Lucas headlamp glass of old, and it cant hold a candle up, (Pardon the pun), to a modern headlamp when it comes to brightness; so why wouldn't I want to fit an LED?

A smaller battery would give me more space in the battery compartment to fit the enormous coil that came with my ignition kit.

Kind Regards


Gavin

Its illigal here too with LED headlight bulbs but I have never been pulled for having a too bright headlight.

The law is also daytime running lights and my old setup couldn`t really be seen a night, neverming during the day!

One stubling block in the uk could be MOT. We don`t have that here for veteran vehicles.

LED's are only illegal for vehicles after type approval was introduced in 1986 and after that point E marked bulbs must be used, pre 86 do not need E marked bulbs.

Thank you kommando for your comment. Okay, so now I feel emboldened to fit an LED headlamp. Given that there will now be a much less current draw, could I get away with a 3AH battery? I'm thinking of a Colman's-Mustard-tin-sized job..

Unless you are really tight for space 7ah is a good balance between but a 3ah would work too, it has to cover the periods when the charging is under the load which will be decreased. It all depends on the Ignition system fitted and what it gets up to at low voltages. I run a 5W LED in the pilot bulb position which is bright but with everyone now running daylight lights a full headlamp LED is seen better which I also have fitted.

Gents .. You are far ahead of me ... Where can a person buy a 12v LED bulb that will fit a Brit reflector? I'm interested in fitting a LED in two Gold Stars. Another Goldie has a 'sealed beam' US made/sold auto halogen light that's nice and bright but a bit large for the bucket space.

You know you want a "BPF" one? Another on the right-hand side of The Pond.

Depending whether the bike has a 'half egg' or 'flatback' bucket, if you replace the sealed-beam with a lens/reflector with a separate bulb that plugs into the 3-spade H4 plug, you know the plug ends up right at the back of a 'half egg', in the narrowest part, or in the rubber 'bathtub' of a flatback? Goffy's website picture appears to show the LED bulb is widest at the rear and slightly longer than the standard H4 bulb 'n' plug? CRDC's H4 LED is also widest at the back but he doesn't have a picture for length comparison. frown

Hth.

Regards,

Gavin & Stuart ... Thanks a bunch for the LED headlight contact info. I'll be ordering from Paul Goff, he has several other interesting 'treasures' too.
