Blackburn Mars 3.0 rear LED light



Ideal commuter rear light offers excellent visibility and good value too

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Blackburn mars 3.0 led rear light is a very smart, tidy package with a series of extremely bright LEDs housed within. Patented design features throughout ensure that this isn’t something that can easily be copied.

Innovative features such as amber side sections allow other road users and pedestrians to see which way you are facing and the light output is impressive for a unit of this size. The clarity of illumination is staggering, even on misty, wet evenings inI could be seen from well over 500m away.

There are the usual fafs when mounting the light bracket but once it is in place that’s the end of the story as the light itself will simply clips in and out of its bracket so you can take it off the bike if it's parked up somewhere unattended. Changing batteries is again the same sort of deal as with other bicycle lights, it is a case of three small screws needing to be undone. It’s unlikely that you would carry spare batteries with you on a ride but if you did it would be handy to carry a screwdriver and have something to drop the screws in while you do the battery switch. Make sure the screws go back in tightly and correctly to maximise the watertight design of the Mars 3.0.

The build of the unit is to the quality you would expect from Blackburn with a water resistant casing to protect the internal electronics and tough, durable plastic casing to help safeguard the light from knocks and bumps. Blackburn are confident enough of its quality to give the Mars 3.0 a lifetime warranty.

Because this is an LED based light unit the battery life is high, in this case Blackburn claim an average lifespan of around 150hours (when in flashing mode) enough to see you through a winter of an hour's commuting a day in the dark .


A very good light for the money. Anything that dishes out this much in the way of visibility especially around 3 sides of your bike has to be worth considering. Be safe, be seen. test report

been back on 2 wheels for a couple of years now and this
is the onlt rear light I've had .... the 2010 version
claims "tool free" battery changes and has a new mount
by the look of it - still as you say stunning little
light  1

btw - on the subject of water tightness ... mine's been
completely submerged for a minute or so after a trail
spd moment and was completely unaffected  1
