fog lights are mounted very low on the cars and are bar shaped or wide shaped, they have sharp cutoff at the top. If used at a low speed these fog lamps increase illumination directed towards the surface of the road. Fog lights help the driver in poor lights, but are mainly used to see in fog, rain and snow. And sometimes dust. If used on s smaller beam they reduce glareback. Fog lights are optional, but once installed can be really helpful in sudden bad weather.

tail lights which are installed at the back of any car bike or even truck are absolutely essential. These tail lights help the driver behind and prevent any accidents from occurring. Tail lights have changed from the plain tail lights to the newer more modern and flashier ones but the basic use and motive of the tail light has still remained the same, to protect lives and prevent accidents.
Tail lights are very helpful. They become brighter when the brakes of the vehicle is applied, thus this gives an indication to the driver behind. This helps the driver stop in time, instead of just driving straight into the car in front.
