im looking to buy xenon bulbs for my car [2000 civic ex]. im sure i dont want a whole kit. just something to brighten my lights.

im looking at the sylvania silverstars but there are different packages of these bulbs.

I red on the sylvania guide that i need 9003 bulbs. i see that for the silverstars there are 9003 hb/2 bulbs, 9003 st/2 bulbs... and on the sylvania guide it also mentions a 9003 su bulb. is there any difference one which bulbs would work and which ones wont... and which bulbs are a brighter white?

 

For the 9003 / H4 application, I'd suggest either the Philips X-treme Power or the Osram NightBreaker. Skip the SilverStars.
