equipped with at least one auxiliary rotating flashing | | light having 4-inch sealed beams and showing amber beams | | of light over a 360 range or an amber strobe, or | | combination of strobes, that emits at a minimum a beam of | | 1,000,000 candlepower and provides visible light coverage | | over a 360 range. When the left wing of a plow is in | | operation and extends over the center of the road, an | | auxiliary light must show the extreme end of the left | | wing. That light may be attached to the vehicle so that | | the beam of light points at the left wing. The light | | illuminating the left wing may be controlled by a | | separate switch or by the regular lighting system and | | must be in operation at all times when the vehicle is | | used for plowing snow on public ways. |
|
| | | (4) A vehicle equipped and used for plowing snow on | | other than public ways may be equipped with an | | auxiliary rotary flashing light that must be mounted on | | top of the vehicle in such a manner as to emit an amber | | beam of light over a 360 angle, or an amber strobe, or | | combination of strobes, that emits at a minimum a beam | of 1,000,000 | | coverage over a 360 range. However, the vehicle must | | be equipped with and must use such a light whenever the | | vehicle enters a public way while in the course of | | plowing private driveways and other off-highway | | locations. The light may be in use on a public way | | only when the vehicle is entering the public way in the | | course of plowing private driveways and other off- | | highway locations. |
|
| | | (5) A rural mail vehicle may be equipped with | | auxiliary lights. |
|
| | | (a) The lights used to the front must be white or | | amber, or any shade between white and amber. |
|
| | | (b) The lights used to the rear must be amber or | | red, or any shade between amber and red. |
|
| | | (c) The lights, whether used to the front or | | rear, must be mounted at the same level and as | | widely spaced laterally as possible. |
|
| | | (d) The lights, whether used to the front or | | rear, must flash simultaneously. |
