Of course I can’t be sure who see threads on this forum vs the Rootes Review, etc… TE/AE Regional Rep/Board Member Joe Parlanti worked on LED lighting and has been selling individual and complete LED light kits for our cars for a couple of years… possibly missing this thread since it goes back to 2011? Joe did a demonstration at the B.A.S.H. in 2015.
There is an ad in the RR just about every month. I installed all of these in our car and have been very pleased.

Choice is good 🙂
