Is it just me or are the E53 stock tails POS....I suspect it has to with a combo of the gasket sealing and the circuit board design. Left tail was rusted through and I purchased a *used* one off Ebay. Again, the left side is shot and I'm leaning on buying a $$$$ brand new OEM tail. Not sure if it's worth it or not , but regardless we have a state inspec. coming up, so I need to get this tail fixed soon. My indy has a shop that will just do the sticker, but I have not needed to drive to my Indy for awhile (he's quite a drives away from me)

I have seen the aftermarket LED tails and personally, I think they look like crap.

It's not the bulbs as I put in fresh bulbs...
And it's not the harness...even though it did get a but rusty from the original set that got leaky leaky and cause corrision on the wiring harness/contacts.
That was resolved and cleaned up and was working fine on the ~second~ used tailight. Tested it with a MM as well.

The CEO is probably planning to keep the X for another 2 more years and I want to do is replace the tails with a working solutions for another 2 more years.

It's not a easy task for me (as there is a full blown stereo install), etc and quite a bit of work needs to be undone/done to get access to the tails.
