Frequently Asked Questions

Q: How does the gravity sensor work on the LED shoulder warning light?

A: The SHINEKNOT UT21 features a built-in G-sensor (gravity sensor) that automatically detects whether the lamp is positioned vertically or horizontally. When worn on a shoulder clip, it intelligently switches between side-flash and top-flash modes to ensure maximum visibility in all directions without any manual adjustment needed.

Q: How long does it take to charge the LED shoulder warning light and how long does it last?

A: The UT21 charges via a standard Type-C USB cable and reaches a full charge in approximately 40 minutes. Once fully charged, the 640 mAh lithium-ion battery provides 20–25 hours of run time depending on the mode selected — making it ideal for extended security patrols or overnight operations.

Q: Is the shoulder warning light waterproof?

A: The UT21 is rated IPX4, meaning it is splash-resistant and can handle rain and light water exposure without issue. It is not designed for full submersion, but it is fully suitable for outdoor use in wet weather conditions.

Q: Can the LED shoulder light attach to surfaces other than clothing?

A: Yes! In addition to the shoulder clip, the UT21 has two powerful magnets built into its base, allowing it to be mounted on any metal surface — including vehicles, metal poles, tool boxes, or equipment — making it extremely versatile for both wearable and stationary use.
