The light from HID is much brighter and often brilliant white or blue-white.

Most vehicles are equipped with Halogen bulbs that are small bulbs that are replaced from under the hood behind the headlight bezel assembly.
They have a twist turn method generally to remove/replace hiowever they cannot have your hand come in contact with the glass bulb as the oils on your skin will in fact reduce the halogen bulbs life as it gets extremely hot burning the oil off the lense shortening the bulbs existence.
Remember to replace the bulb with the proper bulb as you may find two or three different applications of halogen bulbs for the same vehicle, they all have a purpose, they go from bright to brighter to brighter each increase in candle power also increases in price of the bulb, a typical standard priced Halogen is approximately $9.95 and up.
