Are there any decent aftermarket running lights out there ? Both of mine are flaky with moisture. 2011 GL550.. thanks for some direction and brand names .. Bill

Do they still work overall?

I'd just separate the lens, cleanup the water and reseal them. Should be good as new!

 

Found a pair of Revision lights on Ebay for $42.50 each. Seem like decent quality ..will see how long they last .

 

I bought 1 new aftermarket replacement from a random vendor on eBay for a failed light (~$28), and upon receiving the part, I saw no difference in the housing quality; but the lighting color was white (~5500k), not yellowish (~4300k) like the other working OE lamp, so I had to buy another light to replace the other side too, and hope it was the same color light since I didn't buy a pair, and turned out it was the same.

A year later they are still fine with no condensation infiltration; and I have them set to be on all the time as daytime running lights (DRLs).
I wouldn't recommend buying them separately as I did, but here are the links that I used:

Yes, the seller is in China, but only took 2 weeks to receive each lamp.
The quality on these "copies" is so good, it makes me think MB is buying their OE parts from China, and the OEM is selling "aftermarket" out their backdoor.
