				CFR 571.108 ). Light Emitting Diode (LED)
				lamps that meet applicable FMVSS or SAE Standards or SAE Recommended Practices
				are acceptable.

				alternately flashing signal system that conforms to S5.1.4(b) of the FMVSS 108
				(
				49
				CFR 571.108 ) and Section 12-805 of the Code.
				A separate circuit breaker and a master switch shall be provided for this
				signal system. When in its "off" position, this master switch shall prevent
				operation of the eight lamp system; shall prevent operation of any lamps
				mounted on the stop signal arm panel required under subsection (hh); and shall
				prevent operation of any electrically controlled mechanism that would cause the
				stop signal arm panel to extend. The controls for the eight lamp flashing
				signals, the stop signal arm panel, and the service entrance door shall be
				arranged so as to provide for the following sequence of operations while the
				engine is running:
1) Place the alternately
				flashing signal system master switch in its "off" position. Close and secure
				the service entrance door. Actuate the alternately flashing signal system hand
				or foot control. The alternately flashing signal lamps of either yellow (amber)
				or red color shall not go on.
2)
				With the master switch "off" and the hand or foot control actuated, open the
				service door. The alternately flashing signals of either color shall not go on
				and the stop signal arm panel shall not extend.
3) Deactivate the hand or foot control. Place
				the alternately flashing signal system master switch in its "on" position.
				Close and secure the service door. Then open the service door. The alternately
				flashing signal lamps of either color shall not go on and the stop signal arm
				panel shall not extend.
4) Close
				and secure the service door. Actuate the alternately flashing signal system by
				hand or foot control. A yellow pilot lamp in the view of the driver and the
				yellow alternately flashing signals shall go on.
5) Desecure but do not open the service door.
				The yellow pilot and the yellow alternately flashing signals shall go off. A
				red pilot lamp in the view of the driver and the red alternately flashing
				signals shall go on. The stop signal arm panel shall extend.
6) Fully open the service door. The red pilot
				and red signals shall remain on and the stop arm shall remain
				extended.
7) Close but do not
				secure the service door. The red pilot and red signals shall remain on and the
				stop arm shall remain extended.
8)
				Open the service door. The red pilot and red signals shall remain on and the
				stop arm shall remain extended.
9)
