The Blackburn Mars 2 rear light is a great extra bike light in addition to your main lighting system. With a 15 lumen output the Mars 2 clicker light will enhance your visibility in low light conditions. Simple strap mounting fastens the bike light on your bars with a quick ‘Click’, and you’re ready to go.
Right price, super easy to use & if it breaks, falls off or is stolen I'll just buy another.

Probably the best battery operated rear light one can own under 10 pounds. Easy to use and disassemble. Good visibility from the sides as well.

I have had this light for a while now and as much as it may not be the brightest on the market it is certainly the easiest I've used. I would buy another again

What are bike lights?
Bike lights are vital accessories which attach to your handlebars, seatpost, helmet, bag or jersey. Their function is simple – to help you to see and be seen.
Who needs bike lights?
Everyone needs bike lights! It’s a legal requirement to use front and rear lights on your bike between sunset and sunrise, but they are also useful when visibility is poor – in the fog for example.
What are the choices?
Light technology is ever evolving and the choice is enormous. Always think “the brighter the better” and look for a higher lumen output when choosing. There are lights that run on batteries or beams which can be recharged via plug or a handy USB socket (great for topping up at work). Some lights have battery packs and most have a selection of modes to choose from. You’ll definitely need the brightest lights if you ride wooded trails as you’ll really need to see where you’re going!
What should I buy with them?
Spare batteries are handy if your bike runs on these, as is a charger if it’s rechargeable. Spare mounts are always useful, especially if you have more than one bike. A helmet mount points the beam where you’re looking, rather than the direction your bike is pointing.
Don’t get caught out – a spare back up light is a great purchase in case your ride goes on longer than anticipated or the lights go out earlier than expected.
