What is Diffused Beam?

A diffused beam refers to a lighting technique in which light output is evenly distributed over a large area without sharp shadows or intense light beams. The aim of diffused beam lighting is to create soft, diffuse and even lighting that minimises sharp contrasts and creates a comfortable environment.

Where can you find Diffused Beams on your vehicle?

Diffused Beams occur in several places in and around the vehicle to improve visibility, safety and possibly aesthetics. Diffused beams are mainly used in the low beam lights, fog lights, rear lights and in the brake lights.

1. Dimming lights

In headlights, a diffused beam is often used for low beams. Diffused beam low beams distribute the light evenly across the road, giving the driver a wider field of vision without dazzling other drivers.

Fog lights

Diffused beams are also used in fog lights. The even distribution of light helps to reduce glare caused by fog, rain or snow, giving the driver a clearer view of the road and any obstacles.

3. Rear lights

In reverse lights , diffused beams are used to alert other road users to the vehicle’s presence from a safe distance. The even distribution of light minimises harsh light beams that could dazzle other drivers.

Brake lights

Diffused beams are also used in brake lights to provide clear and rapid signalling when a vehicle is braking. This gives drivers approaching from behind sufficient time to react without being dazzled.
