The Knog Boomer 1 rear bike light is a great safety light for commuters and regular riders. It’s water resistant, very compact and pumps out a strong 30 lumen beam.
From the compact rear bike light you get long burntimes of up to 72 hours so you don’t have to change batteries often.
The Knog Boomer 1 comes with 4 brightness modes to choose from including Random Strobe that creates an unusual light source on the road to attract driver’s attention.
Great little light for easy on/off switching between bikes or taking with you on the move. Very bright also so ideal Rear light to make sure you're seen. Only -ve is the rubber strap does seem a little weak so I'm wondering how long it will hold together! Fingers crossed!

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.
