I had a similar problem with a Honda CBR400RR that I am rebuilding. The headlight bulbs are 35/60W which are obviously not very bright (35W) for a headlight, but they're also £25 each and both had blown!

I thought that I could just fit 55/60W H4 bulbs but it turns out that the keying on the bulb base (the pegs) are different, and running the bike with 2x 55W headlights isn't good for the reg/rec and wiring either... forum reports of melting bikes!

So I found some cheap H4 LEDs on ebay and snipped off the tabs, leaving the main (12 o'clock) in place as this fits.

The results are amazing and I'm convinced that they are actually better than the original 35/60W bulbs and they're 1/5th the price!

They are generic H4 LED in the style shown, but I bought from a UK seller (hate waiting for stuff from China!) and cost £4.09 each delivered!
