Grote 46742 Red 4" Rectangular Double-Bulb Clearance Marker Light

The Grote 46742 is a reliable, high-performance signaling solution designed specifically for narrow mounting applications on trucks and trailers. This 12-volt incandescent lamp features a hermetic lens-to-housing seal, which creates a permanent, weather-tight barrier against moisture, road salt, and dust—preventing the internal corrosion that often leads to lighting failure.

Engineered for durability, this marker light is equipped with a 12,000+ hour bulb life, significantly reducing maintenance costs and downtime for your fleet. Its versatile design meets P2 and P3 requirements, and when mounted at a 45-degree angle, it achieves a PC rating, providing full 180° visibility. Compatible with Grote’s Ultra-Blue-Seal® (UBS) pigtails, this lamp ensures a secure, corrosion-proof electrical connection every time.
