Pedestrian Detection with Halogen, Xenon and LED Headlights: The Light Scattering Effect / Fußgängererkennbarkeit bei Halogen-, Xenon- und LED- Scheinwerferlicht: Der Streulichteffekt

Drivers’ ability to detect pedestrians is related not only to the power and range of the vehicle’s headlights, but also to their light scatter. Can pedestrians be detected more quickly with more expensive xenon and LED... [ view full abstract ]

Drivers’ ability to detect pedestrians is related not only to the power and range of the vehicle’s headlights, but also to their light scatter. Can pedestrians be detected more quickly with more expensive xenon and LED headlights than they can with low-cost halogen headlamps? Is it possible to bring about a significant improvement by changing the bulbs in halogen headlights?

Light tests were carried out using an Audi A4 with halogen, xenon and LED lights and with a variety of bulbs in the halogen headlights. The first part of the study concerns the effect of the different halogen bulbs in the... [ view full abstract ]

Light tests were carried out using an Audi A4 with halogen, xenon and LED lights and with a variety of bulbs in the halogen headlights.

The first part of the study concerns the effect of the different halogen bulbs in the Audi A4. The results are discussed and compared with the outcome of a test involving a Series 1 BMW. Furthermore, we will look at whether pedestrians are easier to detect with xenon or LED systems rather than halogen headlights.
