Oregon Auxiliary Lights: 54-Inch Mount Limit and White-Forward Rule (ORS 816.060)

Oregon splits what most drivers call an auxiliary or driving light into two statutory devices. ORS 816.060(1) says that as used in that section, "auxiliary lights" means low beam auxiliary lights, and ORS 816.070(1) says "passing lights" means high beam auxiliary lights. The two sections then impose different duties: both must be wired and aimed under Department of Transportation rules and both must show a white light forward, but only auxiliary lights carry the 54-inch mounting ceiling in ORS 816.060(5) and only auxiliary lights are subject to the equipment-standards clause in ORS 816.060(6). If a light bar is a high beam device, the section that governs it is 816.070, not 816.060.

The height rule is the provision that catches lifted trucks and roof-mounted LED bars. ORS 816.060(5) requires auxiliary lights mounted on a vehicle for highway use to sit at a height of 54 inches or less above the level surface upon which the vehicle stands, measured to the light rather than to the roofline. The statute does not make a higher mount unlawful to install. It routes it instead to ORS 811.515 and 811.520, and ORS 811.515(10) is blunt: auxiliary lights mounted higher than 54 inches shall not be lighted when the vehicle is used on a highway. A roof bar on an Oregon-registered truck is therefore off-highway equipment, lawful to carry and unlawful to switch on once the vehicle is on a public road.

Color is fixed by ORS 816.060(7): auxiliary lights shall show a white light forward. Amber, selective yellow and coloured pods sold as auxiliary lighting do not meet that description, and two prohibitions in ORS 816.350 close the gap. Subsection (11) bars any vehicle from displaying or carrying lighting equipment with a red light visible from directly in front, and subsection (4) reserves blue lights to vehicles operated by a police officer and used for law enforcement. Oregon does allow amber or yellow forward light in one narrow place, fog lights, because ORS 816.230(3) says forward mounted fog lights shall show a white, amber or yellow light while ORS 816.230(4) requires rear mounted fog lights to show red.

Even a compliant white auxiliary light can be used unlawfully. ORS 811.515(7) caps the whole front of the vehicle: when a vehicle is upon a highway a person shall light not more than a total of four lights at any one time that are mounted on the front and that each project a beam of intensity greater than 300 candlepower. Headlights count toward that four. ORS 811.515(8)(a) adds an aiming and dimming duty for any non-headlight above 300 candlepower, which may not be operated unless the beam is directed so that no part of its high-intensity portion strikes the roadway more than 75 feet from the vehicle, and may not be operated at all when low beams are required, meaning within 500 feet of an oncoming vehicle or within 350 feet behind another vehicle under ORS 811.515(6). Motorcycles get a written exception in ORS 811.515(8)(b): a non-headlight may stay lit if its intensity does not exceed the low beams of the headlight system, and no more than two such lights may be operated.

Two further limits from ORS 816.350 apply to the accessory lighting people fit alongside auxiliary lights. Subsection (12) prohibits all flashing lights on any street or highway except turn signals, hazard lights and the headlight flashing systems described in ORS 816.050, so a strobing pod or a flashing amber bar on a private vehicle is prohibited equipment. Subsection (13) allows no motor vehicle other than an emergency vehicle more than one spotlight, and ORS 811.515(9) says a spotlight may not be lighted on approach to another vehicle unless aimed so that no part of the high-intensity beam goes left of the vehicle more than 100 feet ahead. Subsection (14) permits no more than two cowl or fender lights. Light covers are allowed by ORS 816.350(17) on headlights, taillights, brake lights, turn signals and reflectors only if they are removed when those lights are required to be operating.

The hardware itself must meet a standard. ORS 816.060(6) requires auxiliary lights, and any part that tends to change the original design or performance, to be of a type complying with standards adopted by the department under ORS 816.010. Those standards must be consistent with federal regulations or with the Society of Automotive Engineers under ORS 816.010(4), and ORS 816.010(5) provides that a department standard supersedes any conflicting equipment provision of the vehicle code addressed to the same aspect of performance. ORS 816.010(3) and (7) let the department buy lighting equipment on the open market and send it to a recognised testing laboratory, and enforce the penalties in ORS 816.030 to 816.300 when it fails.

A small set of vehicles sits outside the prohibitions. ORS 816.370(1) says ORS 816.350 and 816.360 are not to be construed to prohibit additional parts and accessories not inconsistent with those sections, and ORS 816.370(3) removes road machinery, road rollers, farm tractors and antique vehicles kept as collector items and used for exhibitions, parades and club activities rather than primarily for transportation. Vehicles of special interest registered under ORS 805.020 are deemed compliant under ORS 816.370(2) when the lighting is original manufacturer equipment or its equivalent and is maintained in safe operating condition. Note for future reference that sections 13 to 16 of chapter 278, Oregon Laws 2025, amend ORS 816.050, 816.310, 816.340 and 816.370 operative January 1, 2027; ORS 816.060 is not among the sections that change.

Two separate offences reach auxiliary lighting. Fitting or driving with lighting equipment the vehicle is not allowed under ORS 816.350 is the offence of use of prohibited lighting equipment under ORS 816.360(1), a Class C traffic violation under ORS 816.360(3). Driving without lighting equipment the vehicle is required to carry is operation without required lighting equipment under ORS 816.330, also a Class C traffic violation. Switching on a light in a way ORS 811.515 forbids, including lighting an auxiliary bar mounted above 54 inches, running more than four front lights over 300 candlepower, or failing to drop to low beam within 500 feet of oncoming traffic, is unlawful use or failure to use lights under ORS 811.520, and ORS 811.520(3) makes that a Class B traffic violation except for the subsections listed there, which are Class D.

The money follows the class. ORS 153.019(1) sets presumptive fines of $265 for a Class B violation, $165 for a Class C and $115 for a Class D, plus any surcharge imposed under ORS 1.188 by ORS 153.019(3). ORS 153.018(2) caps an individual at $1,000 for a Class B, $500 for a Class C and $250 for a Class D, and ORS 153.018(3) doubles those ceilings for a corporation. Where a lighting defect leaves the vehicle in such unsafe condition as to endanger any person, ORS 815.020 adds the separate Class B offence of operation of an unsafe vehicle.

Oregon does not run a general periodic safety inspection lane for passenger vehicles, so these rules are enforced at the roadside, but ORS 815.015 also lets the Department of Transportation inspect any vehicle at any time to determine its compliance with the equipment provisions of the vehicle code. To contest a citation, ORS 153.061(3)(a)(A) lets a defendant submit a written or oral request for a trial to the court before the date on the summons, or pay the presumptive fine as a no contest plea through a violations bureau under ORS 153.800 or 153.806. At trial, ORS 153.076(1) provides that violation proceedings are tried to the court without a jury, ORS 153.076(2) puts the burden on the state to prove the violation by a preponderance of the evidence, and ORS 153.076(5) confirms defence counsel is not provided at public expense where only violations are charged.
