Gary Smith

Very impressed with this little light. It replaces a similar light that will no longer charge and the comparison between the two is huge. Much brighter than the old one, it's turned on and off by a long press of the button and has a memory so it stays on the setting you choose, so no more scrolling through the functions. The seat rail mount is a solid clamp which the light clicks securely into and is also held in place by magnets. The flash setting I have chosen is said to have a battery life of 10hrs, but I've only done 4hrs so far. It has a battery indicator and the brake light functions as expected. A quality bit of kit at a good price, delivered on time

I've been using the Gaciron LOOP-100 rear bike light for a few days now, and I'm very impressed. This little light packs a punch with its super bright LEDs, making me feel much safer cycling on the road, especially in low-light conditions. What I love: Brightness: This light is seriously bright. It's visible from a good distance, which is exactly what you want for safety.Smart Brake Function: The brake sensing feature is fantastic. It automatically increases the brightness when I decelerate, providing an extra warning to drivers behind me. Multiple Modes: The seven different modes offer great versatility. I can choose from steady or flashing options depending on the time of day and riding conditions.Magnetic Mount: The magnetic mount is incredibly convenient. It makes attaching and detaching the light a breeze. USB Rechargeable: No more fiddling with batteries! The USB charging is simple and eco-friendly. Waterproof: I've ridden in the rain with this light, and it's held up perfectly. Overall: The Gaciron LOOP-100 is a fantastic rear bike light. It's bright, easy to use, and packed with useful features. The smart brake function and magnetic mount are standout features. Despite the battery life being slightly shorter than I'd prefer, I highly recommend this light to anyone looking to improve their visibility and safety while cycling.

Wow!!! Bright. I still have retina burn!! The light has a magnetic clip and the clip fits on what can be described as an o-ring. But it works. Can be seen when switched on. What’s not to like?

Very happy with this product. Two good options for attachment using a magnet which makes removal simple with no risk of it becoming dislodged while riding. Also very bright light with various flashing modes. It isn’t the cheapest option but I’m glad for having spent a little more and getting such a quality product.

The media could not be loaded. My son lost his old bike tail light since he cycles to school daily, a reliable and high-performing tail light was a must for his safety. search a bit and find the Gaciron Rear Bike Tail Light has been an amazing replacement! This light stands out with its superior performance and impressive features. The magnetic force attachment is super convenient, and the smart brake function adds an extra layer of safety by making him more visible when stopping. With 7 working modes and IPX6 waterproofing, it’s perfect for all weather conditions and situations.
