FMVSS 108 – Federal Lighting Standard for Vehicle Safety
FMVSS 108 (Federal Motor Vehicle Safety Standard No. 108) is a U.S. Department of Transportation regulation that governs all lighting, reflective devices, and signaling equipment on vehicles operating on public roads.
This standard ensures that lighting systems provide the visibility and signaling needed to reduce crashes, especially in low-light or hazardous conditions.
Why Lighting Compliance Is Essential
Lighting is critical to both seeing and being seen. FMVSS 108 outlines specific requirements for:
-
Headlamps, tail lamps, and stop lamps – Including light intensity, beam pattern, and color.
-
Turn signals and hazard warning lights – Ensuring drivers can communicate vehicle movements.
-
Reflectors and side markers – Providing 360° visibility, day or night.
-
Photometric performance – Controlling brightness and direction to avoid glare or blind spots.
-
Installation location and mounting height – Standardizing positioning across vehicle types.
