Truck-Lite 94937 Twist-In Bulb Socket Assembly – 16-Gauge GPT Wire, Stripped End & Ground Ring Terminal (1156 Bulb Included)

Heavy-Duty Serviceability for Replaceable Lamps: The Truck-Lite 94937 Twist Socket Assembly

Simplify routine lighting maintenance and restore reliable signaling to your fleet vehicles with the professional-grade Truck-Lite 94937 Twist Socket Assembly. Explicitly engineered to house and secure stop/turn signal bulbs in vehicle lighting systems, this heavy-duty electrical component provides an exact-fit, twist-in solution for Truck-Lite Model 40 bulb-replaceable lamps. Instead of forcing you to discard an entire lighting assembly over a minor electrical failure, this component allows fleet technicians to replace damaged socket contacts quickly and affordably.

Engineered to Battle Heavy Road Shock and Corrosion 

Commercial vehicles and heavy-duty trailers subject their exterior lights to continuous highway vibration, gravel impacts, and deep pressure washdowns. The Truck-Lite 94937 handles this abuse seamlessly with a durable plastic twist housing that locks tightly onto your lamp lens assembly. Internally, it features high-conductivity tin-plated brass terminals that form a rock-solid, corrosion-resistant path to the bulb base, permanently curing the annoying circuit flickers and grounding drops caused by common road debris. The harness is constructed using heavy-duty 16-gauge GPT copper wire wrapped in a resilient insulation jacket that limits wire-bending fatigue.

Fast Field Installation with 1156 Bulb Included 

Designed to maximize your shop efficiency and lower down times, this 4-inch stop/turn socket kit comes pre-packaged with a high-visibility, heavy-duty #1156 incandescent bulb so it is ready for instant road use right out of the box. The output side utilizes a fast, 2-wire setup: one lead features a clean stripped wire end (blunt cut) for direct splicing into your vehicle’s 12V auxiliary turn/brake lines, while the second wire is fitted with a heavy-duty ring terminal to anchor a permanent chassis ground connection.
