Intelligent Light Detection

Employs a high-precision, smart sensor chip. It accurately identifies vibrations and braking movements.

COB LED and Ensca Lens for Optimal Night Visibility

This innovative combination of COB LED and Ensca Lens technology ensures outstanding night visibility without the discomfort of dazzling light.


The new Q5 taillights utilize advanced lamp beads and lenses, resulting in softer, eye-friendly lighting that provides enhanced safety and stability compared to older taillight technology.

Fog Lenses for Older Models

Employing a straightforward and cost-effective method, fog lenses are utilized to diminish the intensity of light by reducing its brightness.

Optical Lenses for Q5 Models

Utilizing a complex and relatively expensive procedure, the optical lenses are incorporated to maintain the clarity and brightness of the light without causing glare.

Old Model – LED Patch

Using a budget-friendly and straightforward process, LED patches are integrated, but their lifespan is relatively short. Additionally, they may appear more dazzling than other lights with the same brightness.

Q5 – COB Inversion

Despite the higher cost and complexity of the process, the Q5 uses COB inversion technology, resulting in a more stable and long-lasting light. The light also appears softer even when it has the same level of brightness as other models.

Brake Sensing – Integrated Accelerometer

Q5 features a built-in accelerometer and high-performance MCU, which is powered by a three-level digital filter algorithm, ensuring accurate detection of brake activity.

Shock Detection

The light will automatically turn off after 30 seconds of no vibrations and will turn on automatically once vibrations are detected, except when in constant light mode.

Intelligent Light Sensing

Equipped with a built-in light sensor, the light works together with the vibration sensor to initiate and stop automatically, conserving power. However, the strobe and constant light modes are manually controlled and are not influenced by the sensing element.

The SOS and Bright modes are not impacted by the sensing element and can be manually controlled.

Battery Status Display

The indicator light flashes at intervals of 6 seconds, indicating the current battery level.

Flexibility in Mode Selection

Easily switch between flashing modes by clicking the switch, including Flashing, Breathing, SOS, and Shutdown modes.

Waterproof Design with IPX6 Rating

Capable of withstanding harsh environments, this device has an IPX6 rating, indicating its ability to resist water exposure.

Compact & Lightweight

This device boasts a compact and lightweight design, making it easy to carry and transport.

CNC Aluminum Alloy Shell

Constructed with a CNC aluminum alloy shell, this device is resistant to scratches and falls.

    The instruction is kind of unclear. This is my finding after playing around with it. Mode 1 and 2 will only work in dark. Mode 3 and 4 are always on regardless of ambient light conditions. 30 second auto off only works in modes 1 and 2. The brake light function works in all 4 modes. Overall the light is very compact and well-made. Just wished auto off function is available on all 4 modes.
