A traffic signal apparatus is provided with solar panels, a battery source for powering light directional signals during a power outage and a charger linked to the solar panels for re-energizing the battery source. Changing of the light directional signals (i.e. red, yellow, green, arrow) is controlled by a timer connected to the battery power source. In a preferred embodiment, one or more 12 volt batteries, such as those used in an automobile, are connected in series for powering the light signals. The batteries, solar panel(s), charger, connecting cables and the timer may be installed to an existing conventional traffic light signal or, alternatively, on a temporary traffic light signal supported on a post for placement on the ground, preferably in the middle of the road, such as at an intersection.
