Large semi-trucks, also known as 18-wheelers, are an iconic sight on the highways of North America. Semi-trucks are essential for the transportation of goods from one place to another, and they require numerous safety features to ensure their safe operation.
One of these safety features is the lights on the semi-truck that alert other drivers to its presence. These lights have specific names and functions.
Headlights – The headlights on a semi-truck work just like any other vehicle’s headlights. They are used to light up the road ahead of the truck so that it can be seen by other drivers in low light conditions or at night.
Fog Lights – Fog lights are installed on semi-trucks when standard headlights may not provide enough visibility during foggy conditions. These lights are usually mounted lower than the headlights and provide a wider beam of light to help reduce glare from fog.
Auxiliary Lights – Auxiliary lights are typically mounted higher than the headlights and fog lights on a semi-truck. They can be used in combination with the headlights or fog lights to provide additional illumination when needed.
Brake Lights – Brake lights are required on all vehicles, including semi-trucks, as they alert other drivers that the truck is slowing down or stopping. These lights will typically turn red when the brakes are applied.
Cab Lights – Cab lights are installed on most semi-trucks and serve two purposes: they provide additional illumination for working around a parked truck at night, and they can also be used as emergency warning signals when necessary.
Marker Lights – Marker lights are typically installed along both sides of a truck’s trailer and serve as identification for other drivers in low visibility conditions. These lights come in various colors depending on the type of vehicle being operated.
Turn Signals – Turn signals allow drivers to indicate their intent to turn or change lanes without having to use hand signals. All semi-trucks must have turn signals installed so that other drivers can anticipate their movements.
Rear Identification Lights: Rear identification lights are required by law in some states and provinces for all semi-truck trailers over certain lengths. These bright white or red/white alternating flashing lights help identify which side of the trailer is being viewed by other drivers.
ConclusionThe various types of lighting systems found on semi trucks serve different purposes ranging from providing visibility for nighttime operations to helping identify trucks from a distance. All these lighting systems help keep roads safe for all users by providing better visibility and improved communication between drivers.
