On the subject of "bulbs"
Although the HID kits are generally considered to "overload" the charging systems on some small & medium capacity bikes
The bulbs I'm listing here are exactly the same "loading" as OEM (60/55W)
I have them fitted in my 400 CBR & I can highly recommend them

They may be available elsewhere at higher or lower cost but they are a worthwhile "upgrade" to the stock halogen
They may need an "adapter" to fit Mr Honda's lamps, (also available on fleabay), or you could just snip off the tabs* which are spaced differently, as it's highly unlikely that the bulb would move once installed correctly
* I've done this on my Ducati with no problems, using a bulb I got from Netto
