Sylvania says 5008, and other venders have bulbs tat say will work, but the connection is waaaay off. Is anyone running aftermarket back up lights?
Many available on eBay or Amazon. I am partial to my vLED Tritons.
I have been unable to find any. There is a lot of conflicting information regarding LEDs for the 2010-2012.
I can assure you that the LEDs for the 2013 will not work.

I've done some research into it before, when I was looking (about 10 months ago) there were no options I could find. The best thing I could find where 19 watt bulbs that could go in place of out 16 watt bulbs, and I don't think I'd want to chance the heat of those...
