The capabilities of open-source software and microcontrollers were used to construct a device for controlled lighting experiments. The device was designed to ascertain whether individuals with certain color vision deficiencies were able to discriminate between the red and white lights in fielded systems on the basis of luminous intensity. The device provided the ability to control the timing an...

Rear-end collision accounts for around 8% of all vehicle crashes in the UK, with failure to notice or react a brake light signal being major contributory cause. Meanwhile traditional incandescent bulbs on vehicles are increasingly replaced by profusion designs featuring LEDs. In this paper, we investigate efficacy design using novel approach recording subject reaction times simulation setting p...
