The DV8 Offroad FDJL-01 Armor Fenders were designed for maximum clearance when traversing narrow passages that would rip off an ordinary fender. They bolt on with no drilling required and feature a turn signal light that can integrate into the factory harness.
Thank you for your question, these DV8 armor fenders come with DOT compliant LED turn signal lights. They are bright and street legal.
If your JL was equipped with LED turn signal lights from the factory the provided marker lights will set off the dash light. If you JL came with halogen turn signals then the lights work seamlessly.
