I installed a set of United Pacific plug and play full led headlight assemblies on a 2013 Peterbilt 579. Now when the parking brakes are released and the DRL activate, a portion of the trailer clearance lights come on and stay on until the brakes are set and the DRL turn off. Has anyone seen this issue and/or have a solution? Thanks.
