Are you looking to turn your DRL's from white to amber? Gen5DIY has the solution for you. This harness will allow for your DRL's to be amber during the day, still allowing for proper turn signal function, and white at night. This is a nice change up and adds a very cool look to your truck. Harness included a fully sealed relay box so never a worry about water intrusion. Harness plugs inline at each headlight assembly. Install is about 30 minutes. THIS WILL NOT WORK ON TRUCKS THAT WERE UPGRADED FROM HALOGEN TO LED. THIS IS ONLY FOR FACTORY EQUIPPED LED MODELS Please allow 5-7 business days, after ordering, before item ships out.
