question about TopLight Line Plus rear light braking feature
I originally reached out directly to Busch & Muller with this question, but after a week I received no response, so now I'm coming here hoping someone has the answer.
Basically, I'm wanting to install the TopLight Line Plus on two bicycles which already have dynamos and front lights (which are not by Busch & Muller). I'm wondering if the braking feature on this light will work with ANY front headlight, or if it is only compatible with other Busch & Muller lights. Their website is not very clear on this.
Here's the email I sent to them:
Anyone know?

Hello,
Regarding the TopLight Line Plus with BrakeTec technology. The description on your website says "Dynamo rear lights with the BrakeTec function must be connected to Dynamo powered front lights."
What is not clear to me is whether I should expect the TopLight Line Plus to function with (almost) ANY Dynamo powered front light? Or only with SPECIFIC Dynamo powered front lights? Or only with Busch and Muller Dynamo powered front lights? Or only with SPECIFIC models of Busch and Muller Dynamo powered front lights?
I would appreciate more information on the requirements for the BrakeTec function to work correctly.
I was interested in adding your tail light to my bicycle which already has a SON Edelux II head light installed (your competitor, sorry), and was curious to know if I should expect the BrakeTec function to work correctly.

I do not own one, so I could be in error, but I think that taillight senses a rapid reduction in frequency of the AC electric supply, that would imply that the front wheel is slowing rapidly. I have the equivalent light without the braking feature.
Have you looked at Peter White website on that taillight, that may answer your questions.

Well, I never got a response from Busch & Muller, but I found this website: Busch & Müller: BrakeTec
which states in part:
Afaik, the SON headlight does have a connector for a rear light, so I believe it should be compatible.
which states in part:
This is how it works – provided that the lighting system (dynamo) is turned on: A processor inside the rear light analyses signals from the dynamo. If the velocity decreases significantly, the processor registers deceleration and the rear light pulsates very brightly. – The warning function of BrakeTec harmonises ideally in connection with LineTec – so that a wide strip lights up. BrakeTec is an innovation by Busch & Müller.
BrakeTec works only when the rear light is connected to a headlight whose rear light contacts supply alternating current. This applies to all N and senso headlights from Busch & Müller as well as the new LUXOS.

I recall reading somewhere that Supernova taillights might run on DC, in which case I would expect their headlight might not play well with it.
Other brands that Peter White does not sell (example, AXA), if the headlight sends an AC power supply to taillight, I would assume it would work but I certainly could be wrong.

According to what I see on Peter J. White's fine webpage, this taillight isn't designed to handle the full voltage from a dyno. YMMV.
