They should do, but you may need to bend the little tab back so it fits into the socket of the headlight properly.

yeah yeah i know that already, ricky (PDUK) gave me a UK bulb once and told me about the required 'mod' needed to fit UK bulbs in the socket/holder i just needed to confirm that it was the correct bulb to buy that would fit :)

thanks pal :)

Have you done the resistor mod? Otherwise you will burn out your switchgear.

What is the mod, i have uk bulbs but have not done any mods?

same as thewizzard

i have 1 jap and 1 uk bulb and havent burnt out the swichgear..

PDUK never mentioned nothing about it either or does it not apply the NC30?

Well from what i know if its jap spec then its got to have a relay fitted to the lo beam otherwise eventually your left switch gear will give up. Theres info in the forum and vsource for the nc30, it can be adapted to the cbr bikes including the bikes where the lights are on all the time. I done this myself last year so I could use x-treme bulbs.

incase people cant find the link

The Jap spec bulbs are 35w on dipped beam not 55w like H4s - your switchgear will burn out, as mine did before finding the previous owner had made this exact mistake. I think it was Leopard-Pagan who gave info on the mod, maybe search her topics.

im getting one fitted tomorrow, has any who fitted uk h4's used a nail or bought the adapters on fleabay?

or anyone had a go at making adapters?
