Mirrors, Lights and Cameras: Mandatory Visibility Equipment in 2026 F1

Not every component on a Formula 1 car is optimized purely for lap time. A specific category of equipment exists primarily to protect drivers and officials: the visibility systems that allow drivers to see behind them, alert marshals and competitors to a car’s position in low visibility conditions, and provide the FIA with broadcast and compliance footage from prescribed camera positions. Article 14 of the Technical Regulations governs this equipment, with additional provisions for cameras sitting within Article 8 and the standard supply component framework of Article 17.

Rear-View Mirrors

The Specification Requirements

Article 14.2 specifies that every Formula 1 car must carry two rear-view mirrors, symmetrically placed about the car’s centre plane. The reflective surface of each mirror must be 200mm wide and 50mm high, with a tolerance of plus 2mm and minus 0mm applied to those dimensions. The mirrors must sit within a defined reference volume called RV-MIR-HOU, which constrains their placement to a position where they are realistically usable by the driver rather than positioned purely for aerodynamic benefit.

The regulations also specify the optical quality of the mirror surface. Concave sections are prohibited, and the minimum radius of curvature across the reflective surface is set at 400mm. These requirements exist to ensure the mirror provides a reasonably accurate and undistorted view of following cars. A convex mirror creates the illusion of following traffic being further away than it actually is, and a surface with insufficient radius of curvature would produce distortions that reduce the driver’s ability to judge the position and speed of cars behind them.

Despite their regulated specification, mirrors remain a source of engineering tension in Formula 1 because their structural mounts and surrounding bodywork have historically been used to generate aerodynamic benefit. The reference volume constraint in 2026 limits where the mirror housing can be placed, but teams continue to invest engineering effort in designing the mirror stalks and surrounding surfaces to extract aerodynamic value from a component the regulations require them to carry regardless.

Rear Lights

Three Mandatory Lights, Not One

A detail that surprises many fans is that 2026 Formula 1 cars are required to carry three separate rear lights, not the single prominent rain light most viewers notice in wet-weather broadcasts. Article 14.3 specifies the positions and characteristics of all three. The first rear light must be centred on the car’s longitudinal centre plane, positioned between 295mm and 305mm above the reference plane, and located at least 750mm behind the rear face of the front diffuser. This is the central rain light that becomes familiar during wet races.

The two additional rear lights are positioned laterally, one on each side of the car, within the bodywork defined in Article 3.9.2 and at a height between 500mm and 870mm above the reference plane. Their positioning places them at approximately mid-height on the rear bodywork, increasing the visual surface area of the lit car when viewed from behind. All three rear lights are classified as Standard Supply Components under Article 17, meaning they are supplied by an FIA-appointed manufacturer on identical terms to all teams. Teams cannot substitute proprietary light designs or modify the supplied units.

Lateral Safety Lights

In addition to the three rear lights, Article 14.7 requires lateral safety lights on each side of the car. These lights, visible from the side rather than the rear, serve to indicate a car’s presence to marshals and following drivers in conditions where the standard rear-facing lights may not be visible due to the angle of approach. Their presence is part of the broader safety equipment philosophy that makes a Formula 1 car visible to all parties who need to be aware of its position: drivers behind, marshals at trackside, and safety car and medical car crews approaching from any direction.

The combination of central rain light, two lateral rear lights, and side safety lights means a 2026 Formula 1 car carries a considerably more comprehensive lighting system than casual observers might appreciate. The safety thinking behind this comes from incidents where a single point of light failure, or a single rear light obscured by spray in wet conditions, left a car less visible than it should have been. The layered approach connects directly to the 2026 safety regulations, which address driver and marshal protection across multiple systems rather than relying on any single element.

Cameras

FIA Cameras as Standard Supply

Article 8.17 of the Technical Regulations covers cameras and camera housings. The FIA camera units themselves are Standard Supply Components, meaning every team receives the same units from the same FIA-appointed supplier. This ensures that the broadcast footage from onboard cameras uses a consistent image format and quality standard across the entire field, which matters both for the broadcast production team managing Formula 1’s global television output and for the FIA’s use of camera footage in technical and sporting compliance reviews.

The mounting positions for FIA cameras are defined in the regulations, with specific locations prescribed for the primary onboard cameras visible on the car’s bodywork. Teams design the camera housings, which are the aerodynamic fairings and structural mounts surrounding the cameras, as team-specific components. This is one of the areas where the boundary between a standard component and a team’s own engineering work is clearly drawn: the camera inside is identical on all cars, but the housing around it is the team’s own design and may contribute aerodynamic value depending on its location on the car.

Data Recording and Compliance Use

Beyond the broadcast function, camera footage serves an important role in regulatory enforcement. The FIA’s review of race incidents relies on multiple camera angles, and the standardized camera positions specified in the regulations ensure that consistent footage is available from comparable vantage points on every car. This matters most in contact incidents between cars at close range, where the footage from a driver’s own onboard camera can be the most direct evidence of what occurred.

The full electronics framework that governs cameras, their data outputs, and how they integrate with the car’s other systems sits within the broader Article 8 structure detailed in the 2026 F1 Electronics guide. The visibility equipment covered in Article 14 represents the physically observable part of a more complex regulatory picture that includes how the car communicates its presence to the world around it, from the marshalling system signals in the cockpit to the lights visible on the bodywork.
