can i just ask about this lamp unit - am i right in thinking that i should fail this unit as the brake light appears to be affected by the indicators?
the one i saw the other day alternated between brake light LED's and amber indicator LED's on which ever side the indicator was applied and i failed it because
"The illumination of the stop lamp is
affected by the operation of another lamp or the horn."

No need to apologise for babbling! I do it all the time.
Thanks for the input, the rear lights are all led as stock, but the possibility of being less visiable was on the ''dont buy' side of the list 
Ill keep an eye on them, if they produce some better ones, that are less complex, I may pick up a set.
Thanks all.

I would like to offer an opinion here. as a bike tester and a car tester sometimes this problem occurs, I agree with a steady red light for the brake light which I feel after the initial 3 flashes - there is a steady red light.
also there would have to be a more than 50% drop in light source before you can consider a fail.
although I do not agree with fitting after market lighting systems to bike (why change years of research by the manufacture coupled with hundreds of pounds spent in design plus the fact that open electronics to the enviroment can lead to premiture failure so in essance just ride the bike instead of posing - who the hell is going to see this at XX MPH)
reading the MOT Manual I would in this situation pass and advise (not by choice)
PS LED Lights are okay if directly behind but are pants when you move from one side to the other so the intension is motorway driving.
Sorry to babble on about this but I think you get the feeling. but as a tester we are required to follow the book word by word and letter by letter.

Watched the video I guess it will not be allowed in UK. But due to bad video quality it difficult to see the colors. But why does the break lamp flash 3 times?

Theres an awful lot of long words there!
Am I right in thinking then, that 3 sharp flashes are out, but an increase in light emmited is ok?
I agree with the quality of the video problem. For the indicators to be considered a pass, would the brake light LED's have to emit at the same time as the indicator? If the indicator 'forced off' whichever side of the brake was being used to show direction, that would also be a fail?
What would the ruling be with consideration to the indicators scrolling as they do, as opposed to flashing?
I do appreciate the help, I suspected there may be some issues with them, but if I can get a good idea of where the technicalities fail, I may be able to alter the lights programming slightly.
Thanks again.

The brake lamp flashing 3 times is an issue as over here when the brake is applied it has to emit a steady red light,
The indicators may create issues but its hard to see the colours properly due to the quality of the video.
Sorry to burst your bubble LOL , but canbus systems can send a control signal down a single wire to a bulb at a given frequency to emit a given wattage of light, then when the brake is applied, this takes priority over the previous position lamp signal frequency and increases that frequency therefore increasing the light output momentarily, until the brake is released so that the position lamp is therefore functioning again at it normal frequency

Hi guys, Im hoping someone can help me before I spend some money on something I might have to swop around every year.
Basically, are these rear lights legal, and would they pass MOT.
The brake lights and indicators are mounted together in the same unit. there is a video they post up to show the lights in action, but i cant link that at the moment.
In addition, upon braking, the rear lights flash 3 times, prior to showing a solid light, and the indicators dont flash solid, but instead light up in a sequential manner, in the direction of intended turning.
I think, from the video that the brake lights still show when the indicator is flashing, or in this case, scrolling. They advise it is street legal, but they can only confirm that for the US
Thanks in advance.

(I still cant link the video, but it is pretty easy to find on Youtube)
