Brighter lamps definitely increase the burning out of headlights. Using the standard halogens the MB dealer sells, or the standard replacement bulbs at your local parts store will last longer. I once discovered this when I tried a new set of XTRA Bright bulbs. They died at the same time, same day, same hour, same trip, within 6 months of purchase.
I need the numbers for the left light turn signal number. I cannot find it at Wal-Mart. HELP PLEASE AND THANK YOU ASAP!
