J.W. Speaker’s Model 234 tail lights are engineered to defy extreme weather conditions with confidence and reliability, making them the industry’s first LED tail lights to feature SmartHeat® technology. This automatic heating system de-ices the lens surface, ensuring reliable year-round operation in snow, ice, and freezing rain. Designed for use in heavy-duty trucks and other commercial or specialty vehicles, these rugged 4” round tail lights offer drop-in replacement for standard halogen units, providing a seamless upgrade in performance, durability, and safety. Whether you're operating in construction, agriculture, industrial fleets, or transportation sectors, the Model 234 is built to endure and perform under the most demanding conditions.
Built with a lightweight yet robust housing, the Model 234 is capable of withstanding up to 10 g’s of vibration and is sealed to IP69K, making it highly resistant to power washing and steam cleaning. This tail light is not only built tough—it also ensures optimal visibility thanks to superior condensation management and rapid-response LED illumination. Unlike incandescent bulbs, LEDs reach full intensity instantly, giving drivers behind more reaction time and enhancing overall road safety. For legal on-road operation, the DOT-compliant versions of the Model 234 meet all requirements of section 108 of the Federal Motor Vehicle Safety Standards and are clearly etched with their compliance certification on the lens. The lights are also compliant with Transport Canada and select military specifications, further reinforcing their versatility in global and mission-critical applications.
The Model 234 tail lights are available in several configurations, including red stop/tail/turn, amber turn, and clear reverse signal versions, each compatible with standard rubber mounting rings and 3-pin Packard connectors for easy plug-and-play installation. For vehicles using alternate connectors, J.W. Speaker offers versions equipped with an integrated 3-pin Packard wire harness. For enhanced customization, the Flash/Color models require a 6-pin wire harness and offer five distinct lens colors: Amber, Blue, Green, Red, and Clear. These color options, combined with programmable strobe functionality, ensure that your vehicle will be seen and noticed in any environment.
Model 234 Flash lights are especially bold and attention-grabbing, offering a dual-function strobe and turn signal with turn override wire. These models feature three different strobe patterns and include J.W. Speaker’s SmartSync™ system, which enables synchronization of multiple lights in either simultaneous or alternating flash modes. This makes them ideal for applications requiring heightened visibility and signaling, such as emergency vehicles, specialty fleets, or industrial off-road equipment. Accessories such as rubber mounting grommets, plastic flanges, and various trim rings are available to support integration across different vehicle types.
Operating on a 12–24V DC input, the heated versions consume just 8 watts of power to activate the SmartHeat® system, offering efficient de-icing performance with minimal energy draw. These tail lights also meet SAE J595 Class II and SAE J588 strobe performance standards, assuring they’re not only visible but compliant in applications demanding rigorous signaling performance.
With its durable construction, smart heating technology, multiple color and flash options, and legal street compliance, the J.W. Speaker Model 234 is the ultimate solution for reliable, high-performance tail lighting in harsh and variable operating environments. Whether you’re upgrading your commercial fleet or outfitting specialty vehicles, the Model 234 delivers unmatched safety, performance, and peace of mind.
