Designer Kyle McCabe has a knack for inventing, although it took years for his ingenious brake light to be discovered. Shown in a YouTube video in 2013, the light increases in intensity depending on the pressure applied to the brake pedal.

When his invention was shared with Reddit users in March 2016, they immediately recommended that he apply for a patent on the invention, while others wondered why such a thing is not already commonplace on modern cars. Credit: Kyle McCabe via Storyful
