Let's just start here with a little bit of education since the creator of this post can't seem to do any research to achieve his goal.
H.I.D. - High Intensity Discharge lighting is very different than a normal incadescent bulb or a flourescent tube. HID uses a gas pressurized bulb with 2 electrodes inserted. These types of bulbs operate on the principal of excited gasses. The ballast serves a couple of different purposes. The first is to adapt the low input voltage to a number in the 48K volt range. This is the energy used to maintain the excited state inside of the bulb. The ballast also contains a set of capacitor inside that charge when power is given to the unit. These capacitors will fill with a huge amount of energy, then in a instant, they release the energy through the 2 electrodes in the bulb causing a visible spark, which in turn creates the burst of energy needed to start the reaction inside the bulb.
Plugging an HID light into a normal socket will get you nothing. If you are stumped as to why it doesn't turn on when you hit the switch, then you need to do A LOT more reading on the subject before you electrocute yourself.
