that question is on my level 3 exam aswell......
xenon light bulbs work by using a chamber filled with gas and metal halides. When the lights are turned on, a charge is created between two tungsten electrodes, which create an arc of electricity and vapourise the metal halides. The vapourisation gives off a bright light and lots of energy. This energy excites the xenon in the bulb, which gives off the blue light.
Advantages of using this system include;
-environmentally friendly
-they last much longer than halogen lights
-they are significantly cheaper for car companies to install

I believe you are referring to lighting, the visible discharge to do potential difference.
Benjamin Franklin
When there is a sufficiently strong electrostatic charge, it can cause air molecules to ionize, which are then electrically conductive and create a pathway for the discharge of the electrostatic charge.
A lighting bolt is a strike of light through the sky and if your looking this up WOW!:PIt is a lightening discharge between/within clouds and the ground
Thunder and lighting are both products of a thunderstorm. Lighting is a static discharge that usually occurs during a thunderstorm (though it can also occur in some volcanic eruptions) and thunder is the shockwave produced by lightning.
Orange, it is often used in street lighting.
