welcome to m.b.shop!

this guy really knows his stuff!! make sure you look ALL around at his site
www.powerbulbs.com free shipping,located in great britain.
you need a H4 bulb, 9003 is essentially the same,but put out a little less light
consider philips vision plus 50%, osram silverstar + 50%, osram super.
these are 'true' euro bulbs and these are not yet available here[usa].
don't worry no one will ever bother you unless your lights are out of adjustment.
several members here [including myself] have had the philips and really like them.
member 'glen' just bought some of the osram silverstars.
also there is a 'search' feature here that is super. type in "headlight bulbs" or "h4 headlight bulbs" and sit back with a few cold ones and enjoy the reading.
ALL of your lighting questions should be professionally answered at the daniel stern site.
hope this gets you started
