Well, I do not know how HID lights can serve me but I set out on a hunt for them, only because most of my neighbors have got them for their cars, so I didn’t want to be spared out of the list. But the real confusion started with me, when I got into a store to buy them. It seemed to me as if the retailers use some sort of code for these lights like the55w 1600k or an h1 or h7 bulb. I could not decide to buy any of them as I didn’t know which would be the best for my car. I got my work done with the assistance of one of my friends.   I am sure that I am not the only victim of such confusions; there must be other people who may not be having any idea about these lights. So, I have decided to place this piece here.  To start with these I would like to tell you that HID stands for high intensity discharge and HID lights mean bulbs that are capable of discharging highly intense light. These light are many times brighter than ordinary bulbs and with this feature of theirs, they have made the night driving harmless and less traumatic. To talk about the code of these HID lights, I can say that they are categorized according to the capacity of producing the high intensity discharge; even it may refer to the size of the filament. If you find a code with H, like H1 or H2 or H3 like wise. The highest size of the filament available in regard to these bulbs is the H12. You may find the same coding for the halogen bulbs that are available in H fittings. This is particularly done to ensure that the lights correctly fit into your car. You must have commonly heard about the words 35W and 55W in connection with lights.  The letter W stands for watt which is the unit of power. The number denotes the power required by the light to glow.Now, let’s talk about K which stands for Kelvin and is a unit of quantifying the temperature, color temperature in case of HID lights. A light of 1600k would simply mean a bulb with xenon gas that burns at 1600 degrees Kelvin.
