I've had Honda's for the last 6 years but never went to a main dealer, fair too expensive! A few of my mates are mechanics so always bought the bits myself and got them to service the cars (kept recipes of items purchased).
Tried those 'extra bright' bulbs before too on a different car, no noticeable difference at all I found. I usually just head to the local motor factors when I need bulbs and have never had any problems with the bulbs that they supply.
