Truck-Lite 97349 Model 10 Dual-Function Marker Clearance Plug (11.5-Inch Pigtail, 16 Gauge GPT Wire, Fit 'N Forget Stop S.S. 3-Position Connector 282105 to Female .180 Bullet)

Optimize your commercial vehicle's safety profile and unlock seamless dual-stage visibility with the advanced engineering of the Truck-Lite 97349 Model 10 Marker Clearance Plug. Specifically designed to integrate flawlessly with Truck-Lite’s premium Fit 'N Forget Stop/Turn/Tail (S.T.T.) networks and 10 Series lighting configurations, this heavy-duty 11.5-inch pigtail adapter functions as a specialized upper stop pigtail voltage regulator loop for commercial freight fleets, vocational truck builders, and heavy-duty repair shops.

This high-performance adapter plug delivers intelligent vehicle utility right out of the box: it enables compatible marker and clearance lamps to operate across two distinct light output levels. When cruising down the highway under normal operation, your connected lamps emit a standard marker glow; the moment the service brakes are applied, the smart pigtail circuit actively shifts the marker loop to a bright, attention-grabbing auxiliary stop warning. This significantly enhances rear-end and high-profile visibility, protecting your equipment against over-the-road rear-end collisions. For maximum brightness differential, it is optimized for vehicles maintaining a stable 11.9V to 13.5V electrical architecture.

Built to survive the most punishing environmental conditions, the 97349 completely eliminates the hand-splicing mistakes and loose connections common to standard shop wiring. On the primary side, it features a specialized 3-position Fit 'N Forget S.S. connector (Housing 282105) that locks mechanically and tightly onto your primary lamp housing. The secondary side transitions into a corrosion-resistant female .180 bullet terminal. Constructed from robust 16-gauge GPT (General Purpose Thermoplastic) copper conductors configured within a severe-duty 8-wire structural layout, it completely seals out water ingress, road salts, and chemical de-icers to eliminate green-wire terminal rot.
