The fog lamp blanking plate is situated on the front of the vehicle and is attached to the chassis under the bumper. The purpose of a fog lamp blanking plate is to neatly cover the empty space on a vehicle where a fog light would have been installed. fog lamp blanking plates are made of a plastic material and come in a variety of colours and finishes to compliment a range of vehicles, though the most commonly used colours are grey or black which are installed by vehicle manufacturers as standard. Some people find that these do not suit the cosmetic appearance of their vehicle and so may install one in a similar colour to their vehicle. Alternatively, it’s also possible to install fog lights in the place of blanking plates, but this is often at large cost to the vehicle owner.

Some fog lamp blanking plates can be latticed, which can cover up an existing fog light rather than removing it. This has the added benefit of being able to use the lamp, whilst also hiding its appearance. However, this grille makes it more difficult to clean the fog light underneath.
