Overview

The Grote 60311 is a 12V shallow die-cast utility/dome lamp engineered for commercial vehicles, especially exterior sleeper cab locations where space is limited. It pairs a chrome-plated die-cast zinc housing with a clear acrylic lens and a standard 1156 incandescent bulb rated at 32 candlepower. Measuring 5.375 inches in diameter with a 2.0-inch depth, the low-profile design minimizes interference with trim and hardware while providing reliable utility lighting. Drawing 2.1 amperes on 12V DC systems, the lamp integrates easily into typical interior or exterior auxiliary lighting circuits used across tractors, trailers, and vocational equipment.

Specifications & Installation

Installation is straightforward with blunt-cut leads and a screw-mount configuration. The single-lead wiring is intended for power feed, with ground achieved through the metal housing when mounted to a properly bonded surface—reducing harness complexity and installation time. Serviceability is simple: the common 1156 bulb format is widely available, supporting quick maintenance and fleet standardization. The chrome-plated finish helps resist corrosion, and the clear acrylic lens ensures unobstructed light transmission for broad, uniform illumination. Typical uses include exterior utility lighting on sleeper cabs, interior dome lighting on vocational equipment, and general area illumination on service bodies where a compact, durable lamp is required.
