Piaa( H222 ) Xtreme White bulb W5W WEDGE 5W

Very nice and bright white but they last only 5 months, doesn't worth that money.

Real and very marked improvement over the standard halogen bulbs fitted in my 2010 Jaguar XF 3.0 litre

Only had the bulb fitted for 3weeks and they have already blown. I would have expected better given the high price paid

Replaced my H7 bulbs (nightbreakers) with these. They are a little better, but not all the hype and advertising claims about them. If and when they blow I will be returning to Osram. Certainly not worth the money, but I had to pay to find out for myself.
