Description
Headlights have been a part of automobiles back to the beginning when lanterns were used as headlights. Headlights serve one main purpose which is to illuminate the road. Headlight bulbs have evolved from simple filaments to complex HID, LED, and laser designs. Headlights must provide enough light at highway speeds to ensure the safety of the driver but at the same time cannot blind oncoming traffic. Nanotechnology has led to LED micromirror designs that were not possible in the earlier years of the automobile. This course will explore new headlight designs, and break down the differences between Candelas, lumens, watts, Kelvin, and pixels. This course covers generic headlight aiming procedures and DOT regulations. We have also included a section on headlight control systems which illustrates the complex design used in late model vehicles.
