The ECCO 3811A is an LED warning light assembly designed for permanent installation in emergency, safety, and service vehicle applications. Operating on a multi-voltage input of 12 to 24 volts DC, the 3811A provides broad compatibility across a range of vehicle electrical systems without requiring a separate voltage converter. At 2.5 inches in overall height, the unit is built for low-profile flush or surface mounting. It meets SAE Class 1 standards, the highest performance tier for warning lights under SAE J845, making it suitable for use on vehicles where high-visibility emergency signaling is required. Installation and specification are handled by qualified electricians, fleet upfitters, or emergency vehicle technicians.
The ECCO 3811A is intended for permanent installation on emergency vehicles, utility trucks, service vehicles, and other applications requiring SAE Class 1 certified warning output. Its multi-voltage DC input makes it a practical choice for both 12-volt and 24-volt vehicle platforms. The flush and surface mount options allow integration into vehicle body panels, light bars, or mounting brackets. This unit ships as a single assembly and is suited for both new installations and replacement of existing warning light components in professional fleet and emergency service contexts.
Designed as an OEM-style replacement or new-installation warning light assembly for 12-volt and 24-volt DC vehicle electrical systems requiring SAE Class 1 certified warning lighting.
Installation should be performed by a qualified vehicle upfitter or electrician familiar with mobile electrical systems and applicable vehicle wiring standards. Disconnect vehicle power before beginning any wiring work. Mount securely using appropriate hardware for the chosen flush or surface mount configuration, ensuring the housing is sealed against moisture intrusion. Verify input voltage compatibility with the vehicle electrical system before energizing the circuit.
