Re: interior LED lights
V-LEDS, superbrightleds.com, ebay, amazon, putco, people have gotten LEDs from many different sources. There is a thread on here that lists all the bulbs. You'll need need (8) 194 bulbs to replace the main bulbs, 9 if you want to replace the glove box, and 4 fuse type for the vanity mirrors. If you want to replace the map lights, that require some serious work, stripping ribbon cables and soldering single LEDs.
2015 Billet Silver
2012 300SRT, 2009 Jeep SRT, 2006 Charger SRT
Too many mods to list for each, so let's just say a lot was done over the years.
