Bicycle riders always are concerned about the safety of the bicycle lights when it is left in a place away from your daily chores. In such instances, the lights are stolen. Instead, if you have a provision to detach your lights and carry them with you while you are not using the bicycle, it can be a great boon for the bicycle riders.
Here, we have one such feature. You have to use Sugru, a mouldable glue that converts into rubber. Paste the sugru to your bike and attach a proper magnet and light to it. When you want to leave the bike for some purpose, you just have to remove your lights and carry them with you. The only precaution you need to observe is that your magnet must be strong to safeguard your lights.
