The ECCO ED3777A is a low-profile LED warning light designed for permanent flush or surface mounting on emergency and service vehicles. Operating on a multi-voltage power source of 12 to 24 volts DC, this unit fits a broad range of vehicle electrical systems without additional voltage conversion hardware. At 1.38 inches in overall height, the ED3777A maintains a slim profile that minimizes drag and reduces the risk of impact damage in tight clearances. It carries SAE Class 1 and CAT13 certifications, meeting the performance standards required for primary warning use on authorized emergency vehicles. Licensed electricians and vehicle upfitters are the typical installers for this type of unit.
The ED3777A is suited for permanent installation on emergency response vehicles, utility trucks, and fleet service vehicles where a certified Class 1 warning light is required. The flush and surface mount options allow flexibility depending on the vehicle roof or body panel configuration. Its multi-voltage compatibility makes it a practical fit for both 12-volt and 24-volt vehicle platforms, including light-duty and heavy-duty applications common in municipal, fire, EMS, and roadside service fleets.
Designed as an OEM-style permanent warning light for 12-volt and 24-volt DC vehicle electrical systems meeting SAE Class 1 and CAT13 application requirements.
Installation should be performed by a qualified vehicle upfitter or licensed electrician familiar with emergency vehicle electrical systems. Disconnect the vehicle battery before beginning any wiring work. Ensure mounting surface is structurally sound and that all wiring connections are sealed against moisture intrusion per vehicle manufacturer and applicable fleet standards.
