Directing traffic can be a dangerous duty for law enforcement officers, especially at night. IST International offers battery-operated, portable traffic signals with a variety of options. These signals are ideal for use in hurricane-prone areas when the power goes out, and can be funded through FEMA reimbursements. The systems can be deployed from a vehicle or in a charging trailer. The traffic signals will operate for two days with a 1-2 12-volt DC battery, or indefinitely with the solar power model. Utilizing these traffic lights allows officers to be deployed to other, more pressing duty. Traffic signals also can be used on a permanent basis, even programmed to operate through the municipality's computerized traffic system
