The Ravemen TR150 is a compact, USB-C rechargeable rear light that works hard to keep you seen, day or night. Four high-brightness red LEDs give up to 150 lumens in its eye-catching warning flash, visible from up to 1.5km away, while a wide 280° field of view means drivers can pick you out from the side as well as from behind.
Its built-in motion sensor does the clever bit: the light brightens automatically when you brake to warn traffic behind you, switches itself off after 2 minutes standing still and comes back on as soon as you ride off. With IPX6 water resistance for wet Northern Irish roads and three mounting options in the box, it's an easy, no-fuss safety upgrade for commuting and everyday riding.
Available from JMH Cycles, your local family-owned bike shop in Lisburn, Northern Ireland.
