HID Headlights can manage most environmental conditions as well or better than conventional incandescent bulbs, though they do have trouble with extreme heat. However, this is not a major problem as the amount of heat required to damage the bulb is not easy to achieve with normal heat sinks and weather patterns. 

 

The motion of the automobile when the lights are on provides a constant stream of air moving over the car, and is an excellent way to dump excess heat. HID Headlights are more durable than incandescent bulbs, although this is seldom an issue with car lights being used for standard road.This means improvements in the efficiency of car lights is becoming more desirable. HID Headlights are not only very energy efficient, but also are quite rugged compared to incandescent or fluorescent bulbs.

 

A growth in automobile manufacturers usage of HID Headlights may see a significant rise over the next few years. Given the increasing market for gasoline in India and China, it is more likely that gasoline prices will rise than stay steady for perhaps the next decade, no matter what else might be done.  As manufacturing priorities are changing due to public and government pressure, it will be difficult to estimate the expected reduction in fuel use by replacing all car lights. 

 

However,we do already expect a certain amount of HID Headlights in cars. Most digital readouts with the same sort of readout as a digital watch are in fact HID Headlights. It is already normal to find old dials replaced with digital displays, and with such use of HID Headlights, it isn’t a big stretch to use more to provide light as well as information.
