As the saying in C&V land goes; if you feel like using a hammer, walk away and try again later.

My rear light's standlight was not working all that well so while I was waiting for an RMA I decided to take the same light from another bike instead. This is one of 5 or 6 bikes that has this rear light and this is the only one that has stopped working so I consider it a blue monday model.
It however needed some sawing and filing of the mounting bolt. Usually I use a dremel for this but I was doing it by hand this time.

Well, the plastic clip for the bolt snapped off and it slipped inside. In my impatience I decided to open up the light to fix this... and well let's say this light is not meant to be openend.
Now this is totally my fault, but it does give me and others a chance to see what's inside.

And this is another example of Busch and Muller's excellent lens expertise.



The white bit in the middle is the single LED that provides all of the light. Behind the reflector is the lens which spreads out the light to all sides and provides 270° visibility.



There's a big, beefy capacitor on the rear that provides 5 minutes of standlight.


The square rear of the mounting bolt with the broken off clip. That's usually not a problem since the bolt is much longer but when clipped for flush mounting it can slip inside when you remove the light.


It's a shame the light is now broken but it might give me a good basis for something I was planning for quite a while;
a silver metal cover to slide over the black plastic to give the light a more classic look. Well, maybe.

I hope some people enjoyed this look.
