Having owned this Passat since February 2004, I have not needed to change any bulbs on the car, ever. I have however replaced the xenon bulbs a year ago, but the the original bulbs were still in quite good condition (no reddish hue, the sign of bulb going out). Anyway, now, today is the day that I have an official burnt bulb that I need to replace. The passenger side tail light is out. Most likely culprit is the cracked housing, so some moisture can get inside. Driver side is still going strong. I have to say this is quite a remarkable achievement so I thought to share it. Although I have rather low mileage for the age of the car. Just hit 78000 miles (125000 km) the other day. Any similar experiences with the hard to kill bulbs?
