On Twitter, a user under the name @2kspaced, posted a tweet about him using a beacon to light the way for the Uber Eats driver to find the way to his house.
The LED flashlight used, or so-called beacon is typically used by law enforcers to illuminate a certain target. They also serve as a non-lethal force, used to temporarily blind a target.
Generally, high-performance bulbs are used, such as xenon bulbs or high power LED lights. LEDs provide maximum battery life due to their energy efficiency, and the 2000s technology has greatly increased the light output of LEDs.
At one time, xenon bulbs offered the brightest light levels, but recent high-power LEDs are brighter and more efficient than comparable xenon-filled incandescent lamps.
A fellow user had also tweeted the website to buy the flashlight in the picture.
Most people have this flashlight for certain reasons like self-defense, needing to illuminate a certain place to see clearly, or in this case; guide an Uber driver.
