Latham is driving on an unlighted road. A police car appears behind him with lights and siren. The driver of the police car fires a gun at Latham. The police car crashes. Latham tells Schreiber and Deegan what happened. Schreiber and Deegan leave to check it out. They return and tell Latham that the cop broke his neck and died in the crash. Schreiber says they shoved the trooper's car, with the dead cop inside, into a water-filled quarry. Latham turns over the night's collections to Latham.
Subsidiary facts found by an auditor warranted a conclusion of negligence of an operator who on a very dark, stormy night left a motor truck parked for two hours unattended and unlighted with its rear extending onto an unlighted country highway while he sought assistance to repair it, and did not require a conclusion that the operator of another truck which collided with the rear of the parked truck was guilty of contributory negligence.
25950. This section applies to the color of lamps and to anyreflector exhibiting or reflecting perceptible light of 0.05 candelaor more per foot-candle of incident illumination. Unless providedotherwise, the color of lamps and reflectors upon a vehicle shall beas follows: (a) The emitted light from all lamps and the reflected light fromall reflectors, visible from in front of a vehicle, shall be white oryellow, except as follows: (1) Rear side marker lamps required by Section 25100 may show redto the front. (2) The color of foglamps described in Section 24403 may be in thecolor spectrum from white to yellow. (3) An illuminating device, as permitted under Section 24255,shall emit radiation predominantly in the infrared region of theelectromagnetic spectrum. Any incidental visible light projecting tothe front of the vehicle shall be predominantly yellow to white.Any incidental visible light projecting to the rear of the vehicleshall be predominantly red. Any incidental visible light from anilluminating device, as permitted under Section 24255, shall notresemble any other required or permitted lighting device or officialtraffic control device. (b) The emitted light from all lamps and the reflected light fromall reflectors, visible from the rear of a vehicle, shall be redexcept as follows: (1) Stoplamps on vehicles manufactured before January 1, 1979, mayshow yellow to the rear. (2) Turn signal lamps may show yellow to the rear. (3) Front side marker lamps required by Section 25100 may showyellow to the rear. (4) Backup lamps shall show white to the rear. (5) The rearward facing portion of a front-mounted double-facedturn signal lamp may show amber to the rear while the headlamps orparking lamps are lighted, if the intensity of the light emitted isnot greater than the parking lamps and the turn signal function isnot impaired. (6) A reflector meeting the requirements of, and installed inaccordance with, Section 24611 shall be red or white, or both. (c) All lamps and reflectors visible from the front, sides, orrear of a vehicle, except headlamps, may have any unlighted color,provided the emitted light from all lamps or reflected light from allreflectors complies with the required color. Except for backuplamps, the entire effective projected luminous area of lamps visiblefrom the rear or mounted on the sides near the rear of a vehicleshall be covered by an inner lens of the required color when theunlighted color differs from the required emitted light color.Taillamps, stoplamps, and turn signal lamps that are visible to therear may be white when unlighted on vehicles manufactured beforeJanuary 1, 1974.25951. Any lighted lamp or device upon a motor vehicle other thanheadlamps, spotlamps, signal lamps, or auxiliary driving lamps,warning lamps which projects a beam of light of an intensity greaterthan 300 candlepower shall be so directed that no part of the beamwill strike the level of the roadway at a distance of more than 75feet from the vehicle.25952. (a) Lamps, reflectors, and area reflectorizing material of atype required or permitted on a vehicle may be mounted on a loadcarried by the vehicle in lieu of, or in addition to, such equipmenton the vehicle. Such equipment shall be mounted on the load in amanner that would comply with the requirements of this code andregulations adopted pursuant to this code if the load were anintegral part of the vehicle. (b) Lamps on vehicles carried as a load shall not be lightedunless such lamps are mounted in accordance with subdivision (a).Disclaimer: These codes may not be the most recent version.

Plexiglass fry traps were used to investigate the abundance and spatiotemporal distribution of bluegill and redear sunfish fry in Ringneck Pond, a small pond in Central Illinois. High spring turbidity delayed spawning of both species. Bluegill fry were more abundant than redear sunfish fry. Small bluegill fry (14 mm to 20 mm TL) inhabited open water more commonly than large bluegill fry (20.5 mm to 26.5 mm TL) but densities of both size groups were highest in a sheltered bay at the north end of the pond. Bluegill fry avoided the surface in open water. Catch rates of bluegill and redear sunfish fry were higher in lighted fry traps than in unlighted fry traps. Fry collected in lighted traps were generally smaller than fry collected in unlighted traps. Species composition, spatial distribution and length frequency of fry collected in traps and by seining in September were similar. Overwinter survival of bluegill fry was low.
The Council granted formal approval of a plan to replace overhead street signs along Los Alamitos Boulevard from Katella Avenue to Cerritos Avenue. The plan called for unlighted signs, and had been sent back to staff by Council to find out whether cost-saving over lighted signs made the unlighted signs worthwhile. The staff report found that lighted signs cost almost twice as much as unlighted signs with reflective paint, would take twice as long to install due to the higher cost, were more expensive to maintain, and did not last as long. With thanks to staff for the additional information, Council quickly voted to approve reflective signs rather than lighted signs.
We conducted an experiment to determine phototaxis in bonytail Gila elegans, a Colorado River basin endemic fish. We tested groups of 50 protolarvae (6.1-8.9 mm total length) in darkness for 2 h or 4 h with illuminated (lighted) and nonilluminated (unlighted) traps suspended in aquaria in pairs (one lighted and one unlighted, two lighted, or two unlighted); we repeated each trial three times. Among all trials, lighted traps captured 60% (359 of 600) of available larvae, which was significantly more than the 0% (1 of 600) from unlighted traps. Results demonstrate positive phototaxis and suggest larval light-trapping could be used to detect the presence of larval bonytail or to monitor or collect individuals for management of this critically imperiled species. 781b155fdc
