This battery light has LineTec technology incorporated into its compact design. It has two high power LEDs inside the 90mm LineTec light strip. Please note the strip is made from transparent glass that shines red when the light is in use. This light is super bright with 320 degree visibility. It also has senso technology. It is supplied with a standlight that automatically deactivates after four minutes or can be switched off manually.

Weighing in at a very clever concept developed by B&M. Before LineTec cars approaching a bicycle from behind could only see a single rear light spot without being able to judge the distance very accurately. To judge distance the human eye requires spacial relation - especially in 'spaceless' darkness. B&Ms light with the LineTec light strip emit 'spatial' light. With LineTec other road users can estimate the distance to a cyclist much more accurately.

I've fitted it to the rear rack of my Long haul Trucker. I use it every day for commuting and pleasure. The light is easy to use, well made and typical German quality. I think it will last for years.

Questions & Answers (7)
How do you remove and replace the battery?
08 Dec 2019
Mine worked well but the battery needs replacing - do I need tools to do that?
Hi, yes. You need a T10 Torx screw driver or key which is supplied when you buy the light. Thanks. 10/12/19
Note that this light does not have a flashing mode, in contrast the response to the question below.
09 Nov 2017

The reference to a flashing LED in the previous question response was for the battery indicator rather than the entire light. The light itself is constant only.

Can I Use It On Brompton Rear Rack? Is It Waterproof?
06 Jun 2017

Unfortunately you would not be able to use this on a Brompton rear rack. This light uses the 80mm bolt spacing where as the Brompton rear rack uses the 50mm spacing. This light is 'water resistant' but in extreme downpours or submersion some water ingress can occur.

Is There Some Way Of Knowing In Advance When The Battery Will Run Out?
23 Jan 2016
I have been using this brilliant light to commute this winter. Yesterday, I had it on senso mode in the morning but when I returned to the bike to ride home, it flashed at me when I tried to switch it on but would not stay on in any mode. Luckily I had a back up but surely there must be some low battery warning.

There is an indicator LED that flashes quickly when the battery is running low and needs to be replaced.

What Size And How Many Batteries Does It Take?
