The best bulbs I ever have had on my car,brilliant and clear light. Fitted on a C Class with projector headlight ,the beam is well projected on the road without bothering the trafic... The price is not the cheapest, but I think is worth the money, if you compare with the cheaper Chinese bulbs... . Philips it saying than it is a canbus compatible, but on my car I was needed to ad a extra canbus on driver side because from time to time the bulb it was turning off and on...all over everything sort out and I'm please with my item....they come 5 years warranty from Philips. I hope they last at least 5 years. ππ
