Every bike has all these lights as part of its safety features. A Bike Tail Lamp makes a bikes presence known to other vehicles behind it, whereas a brake light advises the driver behind it to be cautious of the vehicle slowing. The brightness of the tail light usually increases when the brake pedal is pressed. The most obvious and important benefit of having a bicycle tail light is the improved health and safety. The powerful light is waterproof and shockproof, and it has the versatility that regular riders require.
