I received 2 headlight adapters for my bike.
It seems that for some reason (which goes against all usual Japanese simplicity), Honda tells you to use H7 bulbs, but doesn't actually make the plug for the bulbs the correct size... so you need to use these £15 each adapters.
One of my bulbs blew the other week, and when throwing it away, Clever Steve didn't actually realise that there was an adapter connected to the bulb... I wanted to get the MTec bulbs too, so I was going to change both bulbs at the same time, so I decided to throw both bulbs away... complete with their adapters.
*sigh*
I'm normally quite observant and careful, and I'm not really sure why I decided to throw away one perfectly functioning bulb.... I guess I just wanted the two new ones to go in at the same time.
Anyway... this is what £30's worth of headlight bulb adapters look like
