What Is the APDTY 138468 License Plate Lamp Socket Assembly?
The APDTY 138468 is a replacement license plate lamp socket and wiring harness assembly designed for 1994-2002 Dodge Ram pickup trucks. The assembly includes:
- Molded plastic lamp socket housing
- Pre-attached wiring harness with factory-style connector

What Are the Symptoms of a Failed License Plate Light Socket?
License plate lamp sockets fail due to exposure to road salt, moisture, and heat from the incandescent bulb. Common symptoms include:
- No license plate illumination – Socket corrosion or melted terminals prevent power delivery
- Intermittent or flickering light – Poor contact from corroded terminals or loose socket
- Burnt or melted socket housing – Visible damage around bulb contacts from overheating
- Water intrusion in socket – Cracked housing allows moisture to corrode terminals
- Bulb falls out or won't seat – Broken retention tabs or warped socket body
- Check engine light or body control module codes – Some Ram models monitor lamp circuit integrity
Driving without a functioning license plate light is a common reason for traffic stops and citations in most jurisdictions.
