GIYO CXWXC USB-C Rechargeable Bicycle Tail Lights with Six Modes, IP66 Water Resistance and Standard, Smart Brake Sensing or RGB Options

Rechargeable rear lighting for road and mountain bikes

Choose a compact rear bicycle light from the GIYO GL09, GL09S, WT26M, WT26 or WT26S range, or the CXWXC CX-TL02S and CX-TL10. The options combine red-light and RGB multicolor versions with different housings, mounting kits and control functions. Each option supplies one selected tail light with the mounting accessories pictured for that option. Multiple lamps in overview photos illustrate mounting positions.

Standard, smart and RGB options

The GL09, GL09 RGB, WT26M and WT26 are standard models. The GL09S, GL09S RGB, WT26S, CX-TL02S and CX-TL10 add smart brake sensing. GL09 RGB and GL09S RGB use multicolor lighting; the remaining options shown use a red lens. All option images list six lighting modes. Select the exact model and mounting kit from the option menu; smart features are available only on the identified smart models.

Smart brake sensing and automatic operation

In the GL09S operating guide, manual mode is activated by holding the button for approximately 0.5 seconds, while a double-click selects smart mode. In smart mode, riding in darkness turns the lamp on, bright conditions turn it off, and stopping in darkness turns it off after approximately 45 seconds. Braking triggers an approximately three-second bright alert. These operating instructions describe the GL09S guide; check the instructions supplied with other smart models for their button sequence and settings.

Mounting kits and frame clearance

The WT26M two-mount option supports seatpost and saddle-bag installation. Its three-mount option adds a saddle bracket. WT26 and WT26S are shown with three mounting positions, while both CXWXC options show separate saddle and seatpost brackets. Compare your saddle rails, seatpost profile and rear luggage clearance with the supplied brackets before choosing. Mount the lens facing rearward and keep bags and clothing clear of the light.

USB-C charging and weather protection

The lamps use USB-C charging, and the option specification images state IP66 water resistance. Close the charging cover completely after charging. The GL09 battery check illustration shows green above 80%, blue at 30–80%, and red below 30%. This indicator behavior belongs to the illustrated GL09 design. Battery capacity, charging input and quoted runtime vary by model as listed below. Runtime ranges depend on the chosen lighting mode.

Model specifications

The source does not provide a separate battery/runtime table for WT26M, so those figures are not assigned from another model. GL09-series charging input is 5 V / 0.2 A for standard models and 5 V / 0.28 A for smart models. WT26 and WT26S use 5 V / 0.2 A and 5 V / 0.28 A respectively; CX-TL02S uses 5 V / 0.28 A and CX-TL10 uses 5 V / 0.5 A.

Housing dimensions and materials

The GL09 body drawing shows approximately 32 × 32 × 30 mm. WT26/WT26S are shown at approximately 30 × 35 × 38 mm, with ABS + PC housings and an approximate lamp weight of 22 g excluding the mount. CX-TL02S is approximately 35 × 37 × 36 mm and 38 g excluding the mount, with aluminum alloy + ABS + PC construction. CX-TL10 is approximately 27 × 24 × 68 mm and 61 g excluding the mount, using CNC aluminum alloy + ABS. Dimension drawings and the model-specific photos below show the orientation of each measurement.
