# CIRYCASE Q4 Front and Rear Bike Lights

Bike Lights: CIRYCASE Q4 is a front and rear bicycle light set with USB-C charging cables and silicone mounting straps listed in the package contents. The listing describes separate selectable lighting modes and gives long runtimes specifically for slow-flash operation, but several battery and mode details conflict across its claims.

## Before you buy

- Listing details are contradictory or unconfirmed: the rear battery is given as 350MAH in one feature and 250MAH in the description, charging is stated as three hours in one claim but 2.5 Hrs front and 1.5 Hrs rear elsewhere, and the headline's 8+12 modes conflicts with descriptions of 2 X 4 front and 2 X 6 rear modes. The package list does not establish a case, and the dimensions and 45 Grams weight are not clearly tied to an individual light or the full set. Check the selected listing for the exact configuration.

## In the box

- 2 front bike lights, white (Included)
- 2 rear bike lights, red (Included)
- 2 USB-C charging cables (Included)
- 4 silicone mounting straps (Included)
- Case (Check selected pack): The listing does not confirm a case in its explicit contents list. Check the selected listing.

## A good fit for

- Cyclists wanting a rechargeable front-and-rear set with several steady and flashing settings.
- Buyers who prioritise listed slow-flash runtime and a battery-level warning indicator.

## Less suited to

- Riders who need a clearly confirmed battery capacity, charging time or runtime for a specific non-flashing mode.
- Buyers who require a carrying case to be confirmed as part of the package.

## Customer feedback

Customer feedback highlights bright illumination, quick USB-C charging and easy fitting, with reports that the stretchy bands accommodate different frame sizes. Reliability and battery life are mixed, including a report of front lights stopping after a few months. That uncertainty matters for riders relying on the listing's long slow-flash runtimes, which are claims rather than guarantees of lasting performance.
- Positive themes: Customers report bright illumination, quick USB-C charging and straightforward installation.
- Negative themes: One customer report describes the front lights stopping after a few months.
- Mixed feedback: Battery life and reliability receive mixed feedback, with both long-lasting use and a reported early failure described.

## Frequently asked questions

### How long do the lights run on a charge?
The listing claims up to 58 hours for the front light and 25 hours for the rear in Slow Flash mode. It does not establish those runtimes for other modes.
### What comes in the listed package?
The explicit contents list names two white front lights, two red rear lights, two USB-C charging cables and four silicone mounting straps. A case is not confirmed by that list.
### Are the lights waterproof?
The listing describes them as waterproof and claims an IPX6 rating. This is a manufacturer claim, not an independently verified rating.
### Are the battery and charging specifications consistent?
No. The rear battery capacity and charging-time claims differ within the listing. Check the selected listing to confirm the version and specifications.
