The Ion T-Series lights are made up of several high-intensity LED bulbs that flash in a strobe pattern to provide a strong, attention-grabbing visual warning signal. They can be configured to operate as a steady-burn warning light or as a strobe light.

One of the key features of the Ion T-Series lights is their rugged and weather-resistant construction. They are made with a tough polycarbonate lens that can withstand the rigors of use in harsh environments. They are also designed to be energy-efficient, with a low power draw that allows them to be used for extended periods without draining a vehicle's battery.

The Whelen Ion T-Series lights are typically mounted on the exterior of a vehicle, either on the roof or on the grille, and can be wired directly into the vehicle's electrical system or operated with a switch or separate controller. They are popular among emergency responders and other professionals who need reliable, high-quality warning lights to help keep them safe while on the job.
