SAE J2042 – Clearance, Side Marker, and Identification Lamps for Vehicles

SAE J2042 is a standard issued by the Society of Automotive Engineers (SAE) that specifies the requirements for clearance lamps, side marker lamps, and identification lamps used on commercial trucks, trailers, and military support vehicles.

The purpose of this standard is to ensure proper vehicle visibility and identification, especially in low-light or high-risk operating environments.

Why This Standard Matters for Vehicle Safety

Proper marker and ID lighting is critical for avoiding accidents during convoy movement, night operations, and off-road missions. SAE J2042 defines the specifications for:

  • Color and placement of lamps based on function and position

  • Photometric performance to guarantee visibility from designated angles

  • Durability of lenses and housings under harsh conditions

  • Mounting location and alignment to maintain consistency across vehicle types

  • Voltage and electrical compatibility with 12V and 24V systems
