HID: High Intensity Discharge - layman terms for very bright gas (light) discharge
Xenon: the name of the gas to produce the very bright (HID) discharge
Yes, Xenon is also a colorless, odorless and tasteless element in noble gas group, with an atomic number of 54, and blah .... blaaaah ....., blaaaaaaah ....., blah, blah ...
Alternatively it can also mean "stranger" in Greek.
So the story like this. I was driving at a very sensible speed of 180kmh down the highway, when suddenly i saw a lorry berak a few railway track rocks on the road....and the rocks are bouncing on each lane...
