busch+müller Secula Plus LED Rear Light - StVZO Approved

very reliable

I bought this based on reviews and price. It is my first dynamo light so I have no experience.

The mount is far from ideal. It's like half a mount, in that it only has half the round part to fit around a tube. The mounts from Moon are great- they give a lot of options- mount with different length elastics for different thickness tubes, a slot on the light to fit 2-3 different types of mounts, ..B+M should do that. I did not have a vertical tube to attach to, I had to use a custom horizontal one that gets screwed onto the rack, it's made by a Local shop which actually specialises in electric scooters and ebikes, and had to use zip ties to hold the light on and prevent it from tilting down.

But once that was done, the light has performed flawlessly. The cable has excess length so it will always reach the light. I've had no rain issues, and the few times I've been able to turn around to catch a glimpse of it while riding, it's been bright and glowing red.

So the light works, the cable length is good, but the mount is barely passable. Still, I'll be keeping it on until it dies.

Light and good quality !

Excellent light! Like the style, top performance.
