Is Modifying Car Lights Illegal?

[JasperAnn]

Modifications should not affect the driving safety of oncoming drivers. Here is relevant information about car headlights: Incandescent Lamps: In 1802 at the St. Petersburg Medical-Surgical Academy in Russia, physics professor Vasily Petrov boldly proposed "obtaining light through electricity." In the early 19th century when bonfires, torches, animal/vegetable oils and gas were still primary lighting methods, and electricity was still a novelty, this idea seemed like pure fantasy. Arc Lamps & Incandescent Lamps: Around the same period in 1809, renowned British chemist Humphry Davy discovered electric arcs while conducting electrochemical research. He personally built a large capacitor using 2000 voltaic batteries, producing even brighter and more intense arc light.
