Headlight Lamp 35 W 12 V 8671100001

If you copy and paste the above lamp and google it , it could be the H3 https://www.google.com/search?q=Head...hrome&ie=UTF-8

When I brought my KTM it had some strange headlight/nosecone fitted and to this day iv never found a bulb to fit it or seen a bulb like it.
I took it of and fitted the original back on and hid it in the shed.

Picture would be great but you describe a holder.... if the holder is separate to the housing then it maybe a H1 https://en.wikipedia.org/wiki/H1_lamp

It has 3 metal tangs on it and the earth tang pushes down the side of the bulb earthing it out

3 Tangs sounds like H4.

It's a bayonet fitting

BA20D? That's the only bayonet headlight fitting I know. Usually used on cheap off-brand 125cc bikes.

Yeah that's the one thanks guys for your help .are the any good I mean lifespan and output

They were the bulbs in Chinese 125's. Seem to remember them being a bit crap but good enough to not ride in to a tree at night.

THere is a conversion plug in kit to an H4 I think.
