Smart Ass | The Ultimate Customizable PEV Tail Light

Upgrade your presence on the road with the Smart Ass, the smartest, brightest, and most customizable tail light designed by and specifically for the PEV enthusiast. Whether you’re carving on an Electric Unicycle (EUC), commuting on a bike, or DIY-ing a helmet mount, the Smart Ass gives you total control over how the world sees you.

Intelligent Braking Technology

The Smart Ass doesn’t just sit there-it reacts. Equipped with a high-precision onboard accelerometer, the light detects when you’re slowing down.

Reactive Patterns: Automatically switches to a high-intensity braking pattern when you hit your defined deceleration threshold.
Custom Sensitivity: Use the built-in captive portal to fine-tune exactly how hard you need to brake before the light triggers.

Total Creative Control via WLED

Forget static red circles. The Smart Ass features a 12x6 matrix of ultra-bright LEDs powered by the industry-standard WLED interface.

Infinite Customization: Access hundreds of pre-set effects or design your own animations via the local Wi-Fi captive portal.
Full Matrix: 72 individual pixels allow for scrolling text, complex patterns, and vibrant color gradients that far outshine any stock tail light.

Premium Build & Open-Source Mounting

We believe your gear should be as rugged as your ride. The Smart Ass is built using high-grade materials designed to withstand the vibrations and demands of the road.

Industrial-Grade Materials: The main body is constructed from UV-resistant ASA, known for its high impact resistance and ability to maintain its finish under the sun. The light shines through a high-clarity transparent ABS cover, ensuring maximum brightness and protection for the LED matrix.
Tailored for Your EUC: Every Smart Ass ships with a custom-fit bracket specifically for your wheel, ensuring a rock-solid installation and a factory-finished look.
Open-Source Adaptability: Want to mount it to a helmet, a scooter, or a custom rack? We provide CAD models upon request, empowering you to 3D print a bespoke bracket for any application you can imagine.

Built for the Community

Low Power, High Output: Runs on 5VDC @ 500mA, making it easy to integrate into existing PEV power systems.
Silicone Sealed: The internal electronics are silicone-sealed for added durability and internal component protection.
Certified: Fully FCC and ISED compliant, ensuring you’re using a device that meets rigorous electronic standards.

Note: While the Smart Ass is silicone-sealed for internal protection, it is not officially IP-rated for water or weather resistance. Please use caution in wet conditions.

Disclaimer: Smart Ass is a 5vdc product. Do not plug it into any higher voltage power supply. (Specifically, do not plug it into the headlight port on a LK wheel)
