The toggle light switch was invented in 1916 by William J. Newton. [2] As a component of an electrical wiring or home wiring system, the installation of light switches is regulated by some authority concerned with safety and standards. In different countries the standard dimensions of the wall mounting hardware (boxes, plates, etc.) may differ.
These cams would actuate switches to turn on the lights in sequence. Later Ford cars and the 1969 Imperial used a transistorised control module with no moving parts to wear, break, or go out of adjustment. FMVSS 108 has been officially interpreted as requiring all light sources in an active turn signal to illuminate simultaneously.
The publication noted that the car took 37.5 seconds to go from 0–60 MPH, it was dangerously structurally deficient in a 30MPH crash test with a standard car, and its bumpers were "virtually useless against anything more formidable than a watermelon", all of which made the publication deem the 360 "unacceptably hazardous".

ChromaFlair is a pigment used in paint systems, primarily for automobiles. When the paint is applied, it changes color depending on the light source and viewing angle. It was created at Optical Coating Laboratory, Inc. (OCLI) [later JDS Uniphase and Viavi Solutions] in 1979 and is used by DuPont and PPG. [1] [2]
Full-voltage vs. parking light headlamp on European-market Volkswagen, 2007. Depending on prevailing regulations and equipment, vehicles may implement the daytime-running light function by functionally turning on specific lamps, by operating low-beam headlamps or fog lamps at full or reduced intensity, by operating high-beam headlamps at reduced intensity, or by steady-burning operation of the ...
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
Switches can be designed to respond to any type of mechanical stimulus: for example, vibration (the trembler switch), tilt, air pressure, fluid level (a float switch), the turning of a key , linear or rotary movement (a limit switch or microswitch), or presence of a magnetic field (the reed switch). Many switches are operated automatically by ...
Bulbs used for headlamps, turn signals and brake lamps may be required to comply with international and national regulations governing the types of lamps used. Other automotive lighting applications such as auxiliary lamps or interior lighting may not be regulated, but common types are used by many automotive manufacturers.
