The use of LED’s (light emitting diodes) instead of bulbs in manufacture has revolutionised the cycle lighting market. Units are now much smaller, more powerful, more efficient and more robust.
Don’t underestimate the size of an LED rear light as the output is staggering. With a selection of light modes from static to flashing and every combination in between, rear LED lights are an incredible piece of kit for their small size. Powered by either normal batteries or by USB recharging ports, battery life is incredible especially on flash modes. No wires or battery packs keeps them compact and lightweight and very easy to mount on bikes or on your person, or both. With a price range to suit all budgets, they are a very inexpensive way of ensuring you are seen and some are so cheap we’d recommend buying several and doubling up.
