Vizi-tec's top-tier brake light modulator. It is completely Plug&Play and comes with a Lifetime Warranty. The programmable profile is self-contained, eliminating the need for an external device app or push buttons to operate the unit; Everything is managed through the brake pedal/lever. Users can choose from over 108 thousand unique profiles. The selected profile can be easily reviewed at any time. Smart Technology: Advanced algorithm includes variable modulation to make sure your brake light adjusts to any traffic situation; Whether it's heavy stop-and-go or steady flow. Unlike less expensive options, it won't keep annoying vehicles behind you. Example at low speed: When the rider applies the brakes more frequently (like in city driving at low speeds), the bursts of flashes to the rear brake lights will be shorter. If the brakes are pressed within 0 to 12 seconds(adjustable), the brake light will NOT flash, allowing it to work normally (solid brake light). This feature is especially useful in heavy stop-and-go traffic to avoid bothering the the vehicle behind you. Example at cruising speed: When the rider applies the brakes less frequently (such as at constant cruising speed), the bursts to the rear brake light will be longer. This is particularly important during sudden deceleration at speeds that need quick responses to changes in traffic or other drivers' actions. Studies have shown that a quick flash of a vehicle's brakes will alert the driver behind much faster... and the SupaBrake Modulator does this for you.
