Retro HID 2016 2500 Upgrade Got some time this weekend along with some good weather to get the HID's into the truck. RetroShop did an awesome job as always. We used a set of OEM projector style halogen setups, from a 2015 1500, Retro shop did a full HID conversion to the assemblies. We then installed them into a non-projector halogen setup on the 2500. This required an additional adapter, and a few more resistors, but it all worked out great. I normally like to hide the ballasts behind the headlight assemblies, with some basic brackets, as you will see in the pictures. Next up are the LED fog light replacements, also acquired from RetroShop. We ran out of time this weekend and could not get the fogs installed.
