Answer:
108°
Step-by-step explanation:
Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).
The sum of all interior angles of pentagon can be calculated using following formula

All interior angles in regular pentagon are of equal measure, so

Thus, the measure of each angle formed by the lights on the perimeter is 108°.
