-consists of lighting and signalling devices mounted or integrated to the front, sides, rear, and in some cases the top of the vehicle. The purpose of this system is to provide illumination for the driver to operate the vehicle safely during periods of low visibility such as darkness, to increase the conspicuity of the vehicle, and to display information about the vehicle's presence, position, size, direction of travel, and driver's intentions regarding direction and speed of travel. -This applies the laws of reflections, as light is reflected off cars, people and other objects, which would allow the light to be directed into drivers' eyes, allowing them to see where other cars are, so they can prevent themselves from crashing into them. :headlamps in the dark

A rear view mirror is a rectangular-shaped mirror that is attached to the interior top center of a car's windshield. The rear view mirror has a large enough reflecting surface for the driver to see behind her car, while not being too large to block any area of the driver's forward vision. A rear view mirror has an oblong reflecting surface that allows the driver to remain looking ahead while driving, and still safely see the road and cars behind her by glancing in the mirror. The mirror gives the driver a reflected "rear view" image out the back window of the vehicle she is driving. This helps the driver monitor traffic and road conditions out the back window, as well as enables her to make safe turns and other split-second driving decisions that may become necessary in the midst of traffic. The rear view mirror is only helpful to the driver if it is adjusted correctly. Once the driver is seated in the vehicle, she can adjust the rear view mirror on its pivoting base until she can get a clear view out the back window. Each driver will have a different height while seated in the driver's seat, and the rear view mirror will require readjustment after each new driver, to maintain a clear backward view of the road and traffic.

-Most commonly brakes use friction to convert kinetic energy to heat energy. -Brakes are generally applied to rotating axles or wheels. -Applies the concept of friction, where two surfaces in motion come in contact, converting the kinetic energy of the sudden deceleration into heat energy, when used before a crash, it could reduce a significant amount of damage caused on impact as less energy is used to cause the damages.
