City light issue

[krew53]

I have replaced my driver side city light 3 times this week!! the first 2 lasted for about a day each, and the one I put in last night never worked at all. WTF! These are replacement from the MB dealer... any ideas?

Bad batch of bulbs perhaps. If a box of bulbs was dropped it can weaken the elements.

or if you are installing them yourself, the basic rule is to not touch the bulb's glass due to oils on your hands causing them to overheat and blow

I made sure bulbs were not touched by hand....

Try some bulbs from a different source.
