Performance and Compliance

The Grote 90951-5 is a sealed-beam 5×7 inch (2B1/7×6) LED headlamp engineered for forward lighting on medium- and heavy-duty trucks and other on-road equipment. It operates from 9–32 V for compatibility with 12 V and 24 V systems and connects via a standard H4 3‑pin plug for a straightforward retrofit. Output is optimized for on-road visibility with 886 lumens on high beam and 361 lumens on low beam, providing crisp, white illumination that helps reduce eye fatigue and enhances detail recognition at night. The lamp is DOT compliant to FMVSS 108 (2B1), supporting legal use where a 5×7 in sealed-beam is specified, and serves as an LED upgrade for legacy sealed-beam numbers including 6052, 6053, H6054, and HP6054.

Durability and Integration

Built for fleet duty, the headlamp features a die-cast aluminum housing with a black powder‑coated finish and a hard‑coated, UV‑protected polycarbonate lens to resist impact and yellowing. Fully potted electronics improve resistance to vibration, moisture, and corrosion in harsh operating environments. Typical draw at 12 V is 21 W (1.59 A) on low beam and 33 W (2.54 A) on high beam, reducing electrical load compared to aging halogen systems. The unit’s compact sealed-beam form factor simplifies bolt‑in replacement, while the wide 9–32 V input ensures compatibility across mixed‑voltage fleets. Backed by a 3‑year warranty and weighing approximately 2.8 lb, the 90951‑5 delivers a durable, compliant, and efficient LED upgrade for 5×7 in headlamp applications.
