this because I've seen so many LED tailings out there, specially on Cadillacs with less than 2 yrs old with individual bulbs burnt out that look pretty bad 1/2 tail light lite up and this is OEM!!. With the set up you are thinking, can you replace an individual LED if needed? Or would you have to replace the entire LED pannel? How easy would it be to go back to OEM set up if desired.
