A Warning Triangle. In case of an accident, you should do everything possible to avoid further collisions without putting yourself in harm’s way. The Highway Code recommends keeping a warning triangle in your car.
Organizer. This is not strictly one item but rather something to store other car accessories in. You should always keep a bottle of water and some spare washer fluid in here as well as other bits and pieces.
Jump Leads. Especially if you have an older car, jump leads are one of the essential car accessories you can carry.
Phone Charger. This makes them incredibly useful if you get stuck or lost somewhere, but they are useless with a flat battery.
Ice Scraper. Perhaps the most obvious of the winter car accessories is the ice scraper.
Travel Shovel Kit. Getting stuck in a snow drift is no fun especially if you are stuck somewhere remote. Having a shovel on hand can mean the difference between getting home and being stuck in your car all night.
Body detailing. For those who believe that the looks of a car are everything, a good body detailing work is essential. Highlight your car’s cool features by dressing it up with paints, stickers, and the works.
Novelty horn. If there’s anything fun to change about your car, it is going to be the horn. There are different types and sounds of horns available from car parts dealer these days. The more unique your horn is, the better it is.
Sat-navigation system is also a must. It is completely useless if you don’t have this accessory because you will keep on looking at the map if you don’t know the direction.
