Halogen Fog Light
Automotive
lighting system includes headlight, fog light, stop light and turn signals,
dashboard icons, etc. Today, we are going to introduce fog light.
As its name
implies, a fog light is the light signal that we use in rainy and foggy day. They
may produce white or selective yellow light, and were designed for use at low
speed to increase the illumination directed towards the road surface and verges
in conditions of poor visibility due to rain, fog, dust or snow. Other cars or
pedestrian can notice our car earlier so that it can decrease the incidence of
accidents. However, fog lights cannot be used as daily light. In good
visibility night, the bad influence of using fog light is no less than abuse of
high beam lights.
Halogen lamp has been
applied on automobiles since 1970’s. A halogen bulb is not out-dated; on the
contrary, it is still used by most customers at present for its advantages. It
has longer lifespan than incandescent light, and its manufacturing cost is lower than HID and LED.
A halogen fog light not only increases brightness but also has longer lifespan. When we
observe cars on the street at night, most selective yellow fog lights are car
models with halogen fog light.
Advantages:
Halogen fog light
has more powerful light penetration than LED or HID light in rainy or foggy
day. Thus, this is main reason why halogen bulb won’t be easily replaced by
other light sources. We should choose good light penetration bulb instead of
high luminance bulb to install in our fog light.
Disadvantage:
Because halogen fog light has lower color temperature so that the color is more yellow. In dark
environment, a yellow halogen light is not brighter than LED or HID.
