I installed the OEM Type-S rear side markers on my base 04 TL and the passenger front stop working and the driver front flickers.. Has anybody else had this problem. Also the pigtales for the rear did not fix so well, nevertheless, they are working fine

 

I also have this problem. Can someone help please?

 

I never had this issue and I installed my type-s rear markers almost 3 years ago.

I would suggest to unplug them and see if the problem is still there. Also, check the wires if they are damage or expose and coming in contact with something.
