ihi i bought some osram h4 nightbreaker bulbs for my l3 model but they wont fit in but when you type my model bike into ebay it keeps suggesting the h4 bulband its not a wrong bulb because they fit straight into azx9 which is a h4 aswell, could somebody please help

Yeah the proper bulb is an odd shape. H4 do not fit. You can use h4 bulbs but you need to cut the two locating lugs off.

Alternatively up £20 per bulb for stock kawasaki units.

I've got uprated H4s with the 2'tabs cut off

Yeah, you have to bodge to get non oem bulbs to fit, monkeys!

you also need to either grind off the internal "tab" thats part of the actual headlight assembly, or cut a wedge into the H4 bulb.

thay are nice and white, but they are no brighter than the original bulbs, maybe even a tad dimmer IMO.

if you want brighter you need to go for HID bulbs but at ~£150 for the pair they are not cheap...
