An industrial tower signal light helps you display the operating status of industrial machines. It may feature red, yellow, blue, or green lights. A tower signal light is usually lightweight and simple to set up. Industrial tower signal lights are sold in different sizes and styles. Some lights include an electrical cable and can be mounted as needed. Various lights are equipped with LED bulbs, and as such, will continue to perform for an extended period of time. Tower signal lights may feature aluminum construction so they can withstand sleet, rain, snow and other harsh weather conditions. These lights may also include a built-in buzzer.
