The ECCO ED3705A is an LED warning light assembly designed for emergency and safety signaling applications on vehicles and equipment. Operating on a multi-voltage power source of 12 to 24 volts DC, it fits a wide range of fleet and service vehicles without requiring a dedicated voltage circuit. The unit mounts flush or surface-mounted for a low-profile, permanent installation at just 1.6 inches in overall height. It meets SAE Class 1 and CAT13 standards, making it suitable for high-visibility warning use where regulatory compliance is required. Electricians, upfitters, and fleet maintenance technicians are the typical installers for this type of unit.
The ED3705A is suited for permanent installation on emergency vehicles, utility trucks, road service vehicles, and other equipment that requires a certified warning light. Its multi-voltage compatibility makes it a practical choice for mixed fleets running both 12-volt and 24-volt electrical systems. The flush and surface mount options give installers flexibility when working with varied vehicle body panels and equipment housings.
Designed as an OEM-style permanent warning light for vehicles and equipment operating on 12 to 24 volt DC electrical systems where SAE Class 1 and CAT13 certified warning lights are required.
