SmartHeat® Technology for Reliable Performance
SmartHeat® technology is an advanced self-regulating heating system designed to prevent snow, ice, and frost buildup on LED tail lights, ensuring uninterrupted visibility in extreme weather conditions. This innovative feature automatically activates when temperatures drop, efficiently de-icing the lens without the need for manual intervention.
By maintaining a clear and bright signal in harsh environments, SmartHeat® tail lights enhance safety and compliance, making them an ideal solution for military, emergency, and heavy-duty vehicles operating in cold climates. With SmartHeat®, you can count on consistent performance, reduced maintenance, and improved road safety in any weather.
Installation
The Model 234 tail lights are designed for plug & play installation, making it easy to replace existing 4″ round halogen tail lights with minimal downtime. For the heated versions, ensure the black wire (heater) is connected to activate the SmartHeat® heating system. A 6-pin wire harness is needed for the flash/color models.
