J.W. Speaker Model 234 LED tail lights

Our LED tail lights for transport, industrial, construction, agriculture and specialty vehicles: The Model 234 Flash. This drop-in replacement for four-inch, round LED lights is the newest edition to the Model 234 tail lights. Now available in blue and green, the light has three programmable strobe patterns and is available in SmartHeat®, enabling year-round use while providing superior visibility, extreme durability and unmatched longevity.


Rear-end crashes are the most common type of collision – with roughly 1.7 million rear-end collisions in the U.S. each year, according to the National Highway Traffic Safety Administration. The Model 234 Flash tail lights provide two, four and six strobe patterns that allows the user to activate simultaneous or alternating flash patterns and a two-in-one dual function strobe.


“The Model 234 is our newest offering of LED tail lights to have SmartHeat technology to de-ice lenses,” said Tim Speaker, CEO at J.W. Speaker. “As lighting technologies have advanced, it was important to continue refining our existing lighting to ensure that all vehicles have access to the latest and most effective lighting technologies, regardless of the vehicle they are driving. We are proud to continue our commitment of creating safer driving experiences on and off the road.”


The Model 234 Flash meets safety standards, including the United States Department of Transportation (DOT), Military and Transport Canada. It can be used with original equipment manufacturer (OEM) displays or J.W. Speaker options. Features include:

  • Capable of withstanding 10g worth of vibration
