Fog Lights
Fog lights are designed to aid visibility in fog.
Aside from fog, fog lights are there to aid the driver in a number of low visibility condition where the standard head and taillights may be less effective.
Function of fog lights .
Fog lights are designed to help in visibility when bad weather conditions reduce your ability to see the road ahead. Front fog lights can cut through mist, fog, rain or even dust as they are mounted lower down than headlights in the front of the car.
uses of fog lights
Fog lights are useful when your visibility is decreased such as when it rain or there is thick fog or mist covering the road ahead.
Using your high beams in these conditions can actually reduce your visibility as the bright light reflects off the fog or mist, making it even harder to see ahead.
Incorrect use of fog lights can dazzle or blind road users. The general rule is that you should only use them when you cannot see more than 100 metres ahead, this also applies to headlights. The highway code also states that you must switch both front and rear fog lights off when visibility improves.
You don’t always need to switch on both front and rear fog lights, the front ones should never be used to light the road in normal driving conditions, that’s what your headlights are for. If it’s foggy but you can still see the road ahead, then there’s no need to have them on.
Rear fog lights should always be switched on whenever visibility is poor, they are there to alert other road users of your presence, not just to give you a clearer view of what’s behind you.
