Grote 66151 - 12' 8" Clearance Light Jumper Harness, Two Slim-Line Males to Two Double Females

Reliable Power Delivery for Professional Trailer Lighting

The Grote 66151 Jumper Harness is a heavy-duty electrical component designed to provide consistent, reliable power to clearance and marker lamps. Measuring 12 feet 8 inches (152") in length, this jumper offers the perfect reach for mid-to-long trailer chassis configurations. Engineered to meet the rigorous demands of the heavy-duty trucking industry, the 66151 ensures your vehicle remains visible, safe, and fully compliant with FMVSS 108 lighting regulations.

Precision Engineering and Versatile "Y-Split" Design

This harness features a specialized configuration of Two Slim-Line .180" Male Bullets on one end and Two Double Slim-Line .180" Female Receptacles on the other. This dual-connector "double female" design acts as a high-quality power splitter, allowing you to easily integrate multiple lamps or auxiliary lights from a single power source. It is the ideal "plug-and-play" solution for outfitting clearance/marker lights directly from a front receptacle or main harness drop-out, eliminating the need for unreliable manual splicing.

Built for Durability in Harsh Road Conditions

Constructed with premium 14-gauge GPT wire, the Grote 66151 is built to withstand the extreme vibrations, moisture, and road chemicals common in long-haul environments. The factory-molded Slim-Line connectors provide a compact profile for effortless routing through tight header rails and internal trailer channels while maintaining a watertight, vibration-proof seal. By protecting the integrity of your electrical system, this harness helps reduce maintenance downtime and prevents costly electrical shorts.
