What is Diffused Beam?

A diffused beam, or diffused light beam, refers to a lighting technique in which light output is spread evenly over a large area without sharp shadows or intense light beams. The goal 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

For headlights, diffused beam is often used for low beam dimming lights. Diffused beam low beam dimming lights spread light evenly across the road, giving the driver a wider field of vision without blinding other drivers.

Fog lights

Diffused beam is also used in fog lights. The even distribution of light helps reduce reflection from fog, rain or snow, giving the driver a better view of the road and obstacles.

3. Rear lights

In reversing lights , diffused beams are used to inform other road users of the vehicle's presence at a safe distance. The even distribution of light minimises sharp light beams that could blind other drivers.

Brake lights

Diffused beam is also used in brake lights to provide clear and quick signalling when a vehicle brakes. This gives following drivers enough time to react without being dazzled.
