ECCO 21 Series Lightbars are versatile and powerful warning devices suitable for a range of vehicle types and duties. There are numerous options and lengths available and the lightbars can either be mounted permanently to the vehicle or mounted using an optional roof mounting kit. The 21 Series is suitable for many vehicle applications and features LED modules with TIR optics, a durable aluminum chassis, polycarbonate lenses and a sleek, low profile design. Available in nine standard configurations, the 21 Series can be configured with either centrally controlled or independent flashing warning modules, offering a choice of either 3, 4, 6, 9 or 18 LEDs per module, including dual color options. Stop-Tail-Indicator, worklamp/takedown and alley light modules are also available as well as an integrated Safety Director to control the rear warning modules independently.
