Quick Summary
The G2FS LITH USB-C Bike Tail Light is a rear bike light with red and yellow lighting, dual flash functions and an IPX6 waterproof rating. It is presented as a rack lamp and includes USB-C charging, so the main checks are the mounting setup, charging arrangement and the lighting modes you want to use.
The light includes fog, warning, steady, fast-flash, full-bright and breathing modes. It also has a charging indicator, a low-voltage alert and mode memory, which are useful features if you want a rear light with a little more control than a basic single-mode lamp.

What to Compare Before Buying
- Mounting setup: This tail light is supplied as a rack lamp with two mounting brackets and cable ties. Check that your bike’s rear setup matches the fixing method you plan to use.
- Lighting modes: The light offers six modes. Compare those settings with the type of rear visibility or warning pattern you prefer.
- Charging format: USB-C charging is included. Make sure that suits the cable and charging routine you already use.
- Protection rating: IPX6 is stated for the light. If wet-weather use matters, compare that rating with the conditions you expect.
- Included contents: Confirm that the brackets, cable ties and USB-C cable are the exact pieces you want in the box.
Compatibility, Size and Fit
The light is described as fitting most bike frames, seat posts or bags, but the main decision point is still the mounting arrangement on your own bike. Check the rear mounting space, the surface you want to attach it to and whether the supplied brackets suit the position you have in mind.
What Else You May Need
A compatible place to mount the lamp is the main requirement. If you plan to charge it away from the bike, you will also need a suitable USB-C charging setup.
Before You Decide
Confirm the mounting position on your bike, the six lighting modes you want to use and the USB-C charging setup before choosing an offer. If you need a rear light for a rack, frame, seat post or bag, this model’s bracket and cable-tie setup is the main feature to check.
Using It in Practice
The light includes a quick Fog Light function that can be reached with a double-click from any mode, which is useful when you want to switch to a low-visibility setting without cycling through the full menu. The mode memory feature also returns to the last used setting, so the light is ready in a familiar configuration after each charge or power cycle.
Common Buyer Questions
Does it charge by USB-C?
Yes. A USB-C charging cable is included.
What mounting parts are included?
Two mounting brackets and two black nylon cable ties are named, along with the lamp body and charging cable.
Is it rated for wet weather?
IPX6 waterproof is stated, so that rating is a key comparison point if wet conditions matter.
Rating and Visibility Checks
IPX6 describes protection against powerful water jets, not protection for submersion. If brightness or runtime is important to your choice, compare those specifications for the exact light before deciding.
