Question

high intensity discharge (hid) lamps
traditional halogen lamps use electrical current to heat up a filament, until it glows and emits lights. the advantages of halogen lamps are simple construction, low cost and they can be powered by the vehicles low voltage system. disadvantages of halogen lamps are low energy efficiency and low light intensity.
high intensity discharge (hid) lamps are a type of electrical gas - discharge lamp; they have much higher luminosity and energy efficiency. a typical 35 watt hid headlight bulb produces a much brighter light than a 35 watt halogen bulb. hid lamps produce light by creating an electric arc between its internal tungsten electrodes. the electrical arc is initialed by a high voltage strike of about 23 kv! the arc is then sustained by voltage of about few hundreds volts.
because of the high voltage required by hid lamps, you should pay special attention and follow the manufactures safety instruction when working on hid lamps. the following safety practices apply:

• wear appropriate personal protective equipment.
• do not touch the hid lamps or any other components of the hid system while the hid lamps are on.
• besides high voltage, the hid lamps can also get very hot when switched on, wait for them to cool down before you start working on them.
• consult the vehicles service manual for detailed instructions on the hid system.

what are the main advantages of hid lamps over the traditional halogen lamps?
simple construction.
shines more brightly.
use less power.

Explanation:

The text states that HID lamps have much higher luminosity (shine more brightly) and energy - efficiency compared to traditional halogen lamps. It doesn't mention HID lamps having simple construction (which is an advantage of halogen lamps), and it doesn't say they use less power (it just compares the light output for the same 35 - watt rating).

Answer:

Shines more brightly.
