I have Eurolites and i love them. I had silverstars in for a while, but when I got the eurolites, I just liked them better due to the whiter light. I put my silverstars into my gf's cavalier, and they have been going strong for about 2 years. I've also had my euroiltes for about 2 years with no problems at all.
BTW, Hondaman23, were the lights in your civic Eurolites? They are made by a company called Toucan Industries (same company that makes Ractive and other imports performance parts). My Eurolites had a small toucan on the label as well.
