HOPUT 645-745 is a direct-fit headlight wiring harness designed to restore reliable front lamp power on compatible 2008–2014 Chevy Silverado trucks.

Built to match the factory fitment, the harness provides two lamp sockets and three connectors so you can plug into existing headlamp modules without splicing or guesswork.
