# CIRYCASE Q4 Front and Rear Bike Lights

Lights: CIRYCASE Q4 is a rechargeable front and rear bike light set with separate controls and multiple light modes. Its listed 400-lumen maximum and claimed long runtimes in slow-flash mode may suit riders who want a compact lighting set, but the listing gives conflicting battery-capacity and mode-count details to check before buying.

## Before you buy

- The explicit package contents list names the front light, rear light, USB-C cable and two silicone mounting straps. A separate kit claim is not corroborated by that list, so confirm any additional accessory in the selected listing. The listed dimensions are unusually large for a light set, so verify them if fit or storage space matters.
- The listing is inconsistent about battery capacity and lighting modes: rear capacity is given as both 350MAH and 250MAH, while the title highlight says 8+12 modes, another detail says 4 settings, and the feature text describes 2 X 4 front and 2 X 6 rear modes. The 400-lumen maximum is not broken down by lamp. Runtime figures apply only to Slow Flash mode, so check the selected listing for the configuration you need.

## In the box

- 1 front bike light \(white\) (Included)
- 1 rear bike light \(red\) (Included)
- 1 USB-C charging cable (Included)
- 2 silicone mounting straps (Included)
- Additional kit accessory (Check selected pack): A separate kit claim is not corroborated by the explicit contents list. Check the selected listing for any extra accessory.

## A good fit for

- Riders wanting a front-and-rear light set with multiple claimed modes and rechargeable batteries.
- Buyers who value tool-free handlebar mounting and want lights that the listing also describes for camping or emergency use.

## Less suited to

- Riders who need a verified battery capacity, a single clear mode count or runtime figures for steady illumination.
- Buyers who need a confirmed output for each individual light or precise product dimensions before ordering.

## Customer feedback

Customer feedback highlights bright illumination, quick USB-C charging and easy installation, with reports of good fit and value. Feedback on reliability and battery life is mixed, including a report of the front lights stopping after a few months. For buyers choosing this set, the reported convenience aligns with its rechargeable design and strap mounting, while the mixed durability comments matter if dependable long-term use is a priority.
- Positive themes: Customers report bright illumination, quick USB-C charging and easy installation.
- Positive themes: Some customers report good fit and long-lasting battery life.
- Negative themes: One customer reports the front lights stopped working after a few months.
- Mixed feedback: Feedback on reliability and battery life is mixed.
