Best Tail Lights

I currently run two different LED tail lights. One is an Ascher and has four modes Steady Bright, Steady Low, Fast Flashing and Slow Flashing, I got it off Amazon and it came with a front white light also it was less than $20 and is rechargable. I also have Xoss Enfitnix tail light that is OK it was more money $25 just for the tail light, it is steady, flashes, are acts as a brake light when you stop…I don’t like it as well as the other set.
