Satisfied with these bulbs for 3 years now on several vehicles in effect lighting is more efficient than a standard bulb (Philips Long Life, OSRAM etc) but no more white as can often expect. Nothing like Xenon, really nothing. But compared to the origin and to stay in the nails of the law, they are the best in my opinion. Term life excellent, 60000 Km in 3 years on a motorcycle and it still works perfectly.
