The switch works to dim the lights but makes a constant buzzing noise.
Mount exactly what I was after & used it to mount a Blinder 1300 Front Bike Light.
And mounted it under my bars to keep the top clear, worked great solid etc.
However, the accessory locking nut only took about 1.5 turns before it was tight, which isn't enough for a secure connection. So I needed to grind the plastic locking nut down by 2mm or so, so that there was more like 4 turns to secure it. Easy fix, but a modification I shouldn't have needed to make.
Still 4 stars because after modification great bracket. :-)
Awesome customer service and speedy online response to my query. Purchased suggested items to meet my requirements and very happy with products.
Recommend this N Z business.
