be pneumatically powered to extend a minimum of 25 feet above the ground. It shall stop at any
vertical height and the light head shall rotate 360°. The light mast shall include a remote control
on a 25-foot cord to provide pan-and-tilt and rotation of the lights. The light mast shall retract
completely into a ventilated and drained compartment of the vehicle body. Electrical power shall

a person standing on the ground. The light system shall be interlocked to operate only while the
engine is running. Pneumatic power for the light mast shall be supplied from the vehicle air
brake compressor. If necessary, the air brake reservoir capacity shall be increased to fully extend
the light mast without hesitation and without the air reservoir system falling below 80 psi. Light
mast controls shall include a permanently set air regulator, an air control valve, and a system air
pressure gauge. A red warning light shall flash continuously, in front of the driver, while the
