Our TCILV Series Signals offer a replaceable circuit board inside a polycarbonate UL/cUL listed weather resistant housing. The exterior also has the option to be painted to match your specific needs. TCILV’s can also flash on and off or back and forth, either with a standard red/green LED illumination or with a customized message. TCILV series signs come standard as 120-277V but are available in a low voltage option 12-24V and are compatible with third party relays. Each unit is made in the USA and is backed by a 5-year warranty.
