You folks can talk about your b&m this-and-that, but until somebody on the market designs a dynamo taillight that rivals the dinotte (or any 2-3watt 90+ lumen tallight), I'm not buying another aftermarket dynamo taillight.
My diy cree xr-e/xp-g red led taillight knocks the socks off of my b&m toplight line plus (brake and non-brake version, I have both).
