What are the cargo lights?
Cargo lights are the lighting fixtures used to illuminate cargo-handling areas to improve safety, efficiency, and security during loading, transport, and storage. They cover interior spaces like holds or containers, as well as exterior decks and related facilities in ships, airplanes, trucks, and warehouses.
What cargo lights are and where they’re used
Cargo lights are specifically designed to illuminate cargo handling zones—such as holds, deck spaces, container bays, and warehouse yards—so workers can see labels, seals, pallets, and equipment clearly. They are built to withstand harsh conditions and are distinct from navigation lights or general architectural lighting.
Contexts and configurations you’ll encounter:
- Maritime vessels — interior cargo holds and hatchways, deck and weather decks; luminaires built for damp or salt-air conditions, with sealed housings and corrosion resistance.
- Aviation — cargo compartments on freighter aircraft and cargo-loading areas; fixtures sized for confined spaces with reliable emergency lighting and often dimmable for different phases of loading.
- Road and rail freight — exterior cargo-area lighting on trucks, trailers, and wagons; portable or fixed, operating on 12–24V DC or 110/230V AC, with weatherproof housings.
- Warehousing and container yards — high-bay and aisle lighting to support safe stacking, inspection, and movement of goods; rugged designs for busy environments.
These configurations collectively support safe handling, accurate inspections, and efficient operations during day and night work.
Key features and safety standards
Lighting technology, environmental ratings, power options, and compliance with safety standards determine how cargo lights perform in real operations.
- Technology and light quality — LED fixtures with high energy efficiency, long service life, CRI typically above 80, color temperature around 4000–5000K for daylight-like visibility, and diffusers to minimize glare.
- Durability and environment — housings rated for moisture and dust (IP65 or higher); corrosion-resistant materials; some models are explosion-proof (ATEX/IECEx) for hazardous cargo zones.
- Power and control — electrical supply options (12/24V DC for mobile fleets; 110/230V AC for fixed installations); options include emergency backup power, dimming, and integration with central lighting controls or sensors.
- Compliance and safety — emergency lighting requirements on ships and aircraft, adherence to hazardous-location standards, and local regulations guiding installation, maintenance, and inspection.
These features help ensure cargo lights remain reliable, safe, and compliant across environments and missions.
Summary
Cargo lights are specialized lighting used to illuminate cargo-handling areas across ships, aircraft, road and rail vehicles, and warehouses. They improve safety, accuracy, and efficiency by providing clear visibility in challenging conditions, with LEDs commonly favored for durability and energy efficiency. The best cargo lighting solutions balance brightness, color quality, and robust protection against moisture, dust, and potential hazards while meeting regulatory requirements.
What are the cargo lights on a truck?
Cargo lights, also known as truck bed lights, are lights installed on a truck to illuminate the cargo area for better visibility. They are useful for loading and unloading cargo at night, setting up camp, or accessing tools and supplies in low-light conditions. These lights can be activated in various ways, including using a switch on the dashboard or bed, through an infotainment system, or automatically when the tailgate is opened or the doors are unlocked.

Common features and types
- Location: They are typically mounted near the top of the truck cab or on the sides of the bed itself.
- Light type: Most modern trucks use high-efficiency LED technology, which provides bright illumination and has a long lifespan.
- Control:
- Manual: A switch located on the dashboard, often near the headlight controls, or on the inside wall of the truck bed.
- Automatic: Some trucks automatically turn on the cargo lights when the tailgate is lowered or the doors are unlocked.
- Infotainment system: Some models allow you to control the lights through a touchscreen display.
- Functionality:
- Some trucks have a combined brake and cargo light in a single unit, where a different part of the light illuminates for the brake light and the cargo light illuminates for cargo lighting.
- It's possible to add aftermarket cargo lights, which can include motion-activated options.
Benefits of using cargo lights
- Increased safety: They make it safer to load and unload items in the dark.
- Enhanced convenience: They are useful for camping, off-roading, or other situations where you need to access the truck bed at night.
- Versatility: They can be used by tradespeople working in low-light conditions or by anyone who needs extra light in the truck's cargo area.
What are cargo area lights?
The cargo light is a crucial feature in vehicles, especially trucks, vans, and other cargo-carrying vehicles. Its primary function is to illuminate the cargo area, ensuring that items are visible when loading or unloading, particularly at night or in dimly lit environments.
Is it illegal to drive with cargo lights on?
It is not illegal per se, but many parents and drivers discourage it because it increases the risk of distracted or impaired driving. Law enforcement officers may still pull you over if they believe the interior lighting impacts your driving ability or creates a safety hazard.
When to use cargo lights?
Illumination for Loading and Unloading: They provide essential illumination for loading and unloading cargo in low-light conditions or during the night.
