The lighted ball includes a spherical housing having a transparent portion, a circuit board mounted in the spherical housing, a on-off switch to detect an impact of the spherical housing and a lamp to flash in response to the impact of the spherical housing. The on off switch includes a first vibration switch and a second vibration switch which is positioned an angle with respect to the first vibration switch, and the lamp includes a first light emitting diode and a second light emitting diode which is positioned at an acute angle with respect to the first light emitting diode. The angle may be approximately 90°. The first light emitting diode may be a different color than the second light emitting diode, and the spherical housing includes a controller to receive signals from the on-off switch.
