Using these headlights is a breeze. First, make sure you have all the included parts: 2 Dodge Ram XB LED headlights, plug - and - play wiring, flicker/hyperflash modules, and optional resistors if you have a 2015 truck. The wiring is designed to be easy to connect, so you won't have a hard time installing them. Just match the plugs and make sure everything fits snugly. For 2013 - 2014 model years, you might need to reprogram the OE projector to avoid error codes. And if you have a 2015 truck, don't forget to use the optional resistors. As for maintenance, the UV - coated polycarbonate lens is durable, but you can clean it with a mild automotive glass cleaner and a soft cloth to keep it looking good. These headlights come with a 5 - year warranty, so you can have peace of mind knowing they're built to last.
