A more recent development in bollard technology are bollard covers. They are used by many industries and communities as a cost-effective way to increase safety and refresh old and worn-out-looking bollards without having to completely replace the original bollard. They slip over the existing bollard and can come in a variety of shapes and styles. Because they are easily removable, they can be replaced quickly, and depending on their material they may never need painting and are resistant to scratching and other wear and tear. Traffic bollard covers are typically made of tough recycled plastic and have high-visibility colours to ensure motorists see them. Decorative bollards are used in street areas to enhance display and may come with LED lights to increase visibility and safety at night.
