Here's a quick side-by-side of the new Quad Red with an older 140R (Quad Red is on the left). My 2 cents: The Quad Red is about the same brightness head-on, but it has a better off-angle brightness. I bought it because of the internal battery, the external battery for my 140R always seemed a hassle to attach, one time it even rotated around and down and jammed in my rear wheel causing it to lock up and blow the tire. That was a pucker moment!

If you already have a 140R or other Dinotte light and your happy with it then you don't really need the new Quad Red. If you're looking for a new tail light, the Quad Red can't be beat.

Finally, sorry for the poor video. Use it only for the A/B comparison, it doesn't do justice to how bright these lights really are.
