Sorry, i have to disagree with Jon on the ebay bulbs. I stupidily bought two sets off there, the five pound ones, and after about 2 weeks where the bulb had heated up the bulbs silver covering had bubbled off. It might of just been my bad luck, but who knows. I got mine from a mate @ Carnoisseur Plymouth for £6 a set and have done the job nicely on the fronts and rears. Hope this is some help. Sorry Jon!
