Depending on the head light set up depends on te bulb.
H4 buldbs are twin filament ie they produce both the side light and main beam light source. H7 bulbs are single filament and produce the high beam light. H7 are used for side lights when the light is reflected back into the base of the head light and angled so as not to blind oncoming motorists. I would imagine that your set up would be H4, depends on how it works.
Probably doesnt help, as rambled a little. The manual should say though.
c1h model ? from memory all the new kwakas use an H7 bulb , , the headlight lesnse on them is clear so you can see the face of the bulb - it says on there but if there big there H4 n if there small H7 generally
osram and PIAA do bulbs now which are kinda like the high intensity discharge gas filled bulbs , awesome clear beam of light - reccomended
Which ever size you get, Dont get Halfords…they are feding useless.
I buy 2 the other day, “Extra white light”/ “Extra safety” blur blur blur…i put them in (crap) and went out the next day and bought Phillips lazor Blue. 100% better.
Here’s what Auto Express had to say about Xtreme Power:
This is so new, we could not randomly select test samples, so can’t include it in our assessment. Yet performance of our pre production unit was staggering. Even compared with the current benchmark Plus per cent bulbs, the difference was immediate and dramatic. Philips claim an 80 per cent improvement over standard units, but we think that this is conservative.
The results have been achieved in the same way as the 30 and 50 per cent lamps-by taking the allowed tolerances right to the edge. This time though as well as reducing the filament and burning it hotter, Philips has shrunk the glass casing.
As a result, the gas pressure can be increased for better light output.Engineers have also optimised the geometry and shield position to focus the light where it is needed.
