Product Details

The Dorman 645-523 is a direct-fit replacement headlight connector (head lamp socket) engineered to restore proper electrical connection to your vehicle's headlight assembly. Designed as a drop-in replacement for worn, burned, or damaged OEM connectors, this pigtail socket eliminates the need to replace the entire wiring harness — saving both time and money on the repair.

Key Features:

  • Direct replacement: Matches the appearance and function of the original factory hardware for a hassle-free installation
  • 3-wire female terminal: Correct terminal configuration for a secure, factory-style connection
  • Harness length: 16-inch wire lead provides ample length for routing and connection
  • Durable construction: Built from high-quality materials engineered for long service life and resistance to heat and vibration common in headlight environments
  • Ideal repair solution: Replaces connectors that have failed due to heat fatigue, melting, corrosion, or physical damage
  • Cost-effective fix: Replace only the connector — not the entire wiring harness

Dorman has been a trusted name in the automotive aftermarket for over 100 years, offering OE-quality replacement parts backed by a dedicated team of product engineers in the United States. The 645-523 is part of Dorman's comprehensive line of headlamp sockets and connectors covering a wide range of domestic vehicles.

Lowest Price for what I was looking for. Free shipping ALWAYS helps

Wrong ones want to return

good

On time delivery.

Exactly as expected. Fast, easy, and great prices.

Great quality and pricing. Shipped next day. Only complaint is fedex let the package set 3 days in one location. They blamed it on weather. The depot is 2 hrs from my location. Its been 85 and sunny for the last 6 months. I will no longer purchase any items shipped using fedex.

Smooth Transaction. Would definitely shop here again.
