Said indicator shall be so designed and located that when lighted it will be readily visible without glare to the driver of the vehicle so equipped. [ 1977 ex.s. c 355 s 20; 1961 c 12 s 46.37.220.

(1) Whenever a motor vehicle is being operated on a roadway or shoulder adjacent thereto during the times specified in RCW 46.37.020, the driver shall use a distribution of light, or composite beam, directed high enough and of sufficient intensity to reveal persons and vehicles at a safe distance in advance of the vehicle, subject to the following requirements and limitations: (2) Whenever a driver of a vehicle approaches an oncoming vehicle within five hundred feet, such driver shall use a distribution of light, or composite beam, so aimed that the glaring rays are not projected into the eyes of the oncoming driver. The lowermost distribution of light, or composite beam, specified in RCW 46.37.220(2) shall be deemed to avoid glare at all times, regardless of road contour and loading. (3) Whenever the driver of a vehicle approaches another vehicle from the rear within three hundred feet such driver shall use a distribution of light permissible under this chapter other than the uppermost distribution of light specified in RCW 46.37.220(1).

Head lamp systems which provide only a single distribution of light shall be permitted on all farm tractors regardless of date of manufacture, and on all other motor vehicles manufactured and sold prior to one year after March 18, 1955, in lieu of multiple-beam road-lighting equipment herein specified if the single distribution of light complies with the following requirements and limitations: (1) The head lamps shall be so aimed that when the vehicle is not loaded none of the high intensity portion of the light shall at a distance of twenty-five feet ahead project higher than a level of five inches below the level of the center of the lamp from which it comes, and in no case higher than forty-two inches above the level on which the vehicle stands at a distance of seventy-five feet ahead; (2) The intensity shall be sufficient to reveal persons and vehicles at a distance of at least two hundred feet.

Any motor vehicle may be operated under the conditions specified in RCW 46.37.020 when equipped with two lighted lamps upon the front thereof capable of revealing persons and objects one hundred feet ahead in lieu of lamps required in RCW 46.37.220 or 46.37.240: PROVIDED, HOWEVER, That at no time shall it be operated at a speed in excess of twenty miles per hour.

(1) At all times specified in RCW 46.37.020, at least two lighted lamps shall be displayed, one on each side at the front of every motor vehicle, except when such vehicle is parked subject to the regulations governing lights on parked vehicles. (2) Whenever a motor vehicle equipped with head lamps as herein required is also equipped with any auxiliary lamps or a spot lamp or any other lamp on the front thereof projecting a beam of intensity greater than three hundred candlepower, not more than a total of two of any such additional lamps on the front of a vehicle shall be lighted at any one time when upon a highway.
