 FAQ - Do LED Lights Contain Mercury? - Car Lighting District

LED lights do not contain even the slightest trace of mercury, which makes them the safest alternative for automotive lighting. Other forms of light bulbs, such as the HID bulbs, contain mercury as well as a number of other toxic chemicals that emit vapors into the environment, making them very dangerous. Some of the following light bulbs do contain mercury, and special care should be taken when handling them. [source: LEDlights.org]

What is Mercury?

Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy.
