Stay visible and safe in all weather conditions with the J.W. Speaker Model 274 Heated LED Signal Light—a rugged, efficient, and intelligently engineered lighting solution designed to retrofit standard 2" x 6" oval signal lights. Available in ten different versions, this versatile signal light is engineered to ensure that your brake, turn, and hazard lights remain clear of snow and ice, delivering critical visual signals when visibility is at its worst. The Model 274 features long-lasting, powerful LEDs and J.W. Speaker’s proprietary SmartHeat® technology, which automatically activates to melt snow and ice, ensuring maximum visibility and performance in the harshest conditions. Whether installed on trucks, trailers, or specialty vehicles, this heated signal light helps eliminate downtime and enhances road safety.
Designed for easy installation and broad compatibility, the Model 274 seamlessly retrofits standard oval signal lights and offers flexible mounting options, including flange, grommet, and L-shaped brackets. It supports both vertical and horizontal mounting orientations and is fully DOT-compliant for legal on-road use in the U.S., meeting FMVSS 108 requirements. The DOT certification is etched directly onto the lens for clear, permanent identification. Versions with the Model 274 Flash also include SmartSync™ system compatibility, enabling multiple lamps to flash in either a synchronized or alternating pattern. The 2-in-1 dual-function models provide turn signal override functionality, as well as SAE J595 Class II compliance for strobe lighting applications.
Built to withstand the rigors of demanding applications, the Model 274 signal light features a rugged polycarbonate lens and housing that meet IP67 and IP69K sealing standards for superior protection against dust, water, and high-pressure washdowns. This durability makes the light an ideal choice across a wide range of industries and environments, including agriculture, construction, industrial transport, military, specialty vehicles, mining, powersports, off-road, material handling, truck and bus, and automotive sectors. The Model 274 operates at 12–24V DC and features transient spike protection up to 150V. Heated versions draw 1.2A at both 12V and 24V during tail light operation, while non-heated stop and turn functions draw only 0.15A.
J.W. Speaker’s Model 274 signal lights provide a powerful upgrade from traditional bulbs by delivering more brightness with lower power consumption, enhanced resistance to shock and vibration, and a plug-and-play retrofit design. Backed by advanced thermal management and lighting control technology, these LED signal lights offer unmatched performance and reliability in all weather and operating conditions—giving you confidence and safety from every angle, every time you hit the road.
