Studies have proven that red light has significantly less adverse impact on night vision compared to white lighting. The retina differentiates visual inputs and sends information to the brain. Within the visible spectrum, red has the lowest frequency and helps preserve your night vision as it is the least likely to over-stimulate the receptors within your eye allowing the pupils to remain dilated when visually transitioning between the illuminated area and darkness. When operating within the red spectrum vs white we experience a faster adaption time between light and dark resulting in a safer operating environment.

The color red is often associated with safety and emergency vehicles, subsequently, red lights provide a number of additional safety features. Aside from the safety of those working around the illuminated area, red LED lights are less obtrusive to those driving at night, especially in a roadside situation where there may be active traffic operating. Red lighting also provides the best ability to see detailed information such as labeling on a pump panel, instrument settings, gauges, etc. compared to other colors at night.
