I love this light! I had a near miss recently at a crosswalk where a crossing guard had stopped traffic in a place where there isn’t otherwise a stop sign. School had just started after summer break, so people weren’t used to stopping there. Luckily I got out of the way and I didn’t get hurt, but there was a collision. The adrenaline! I came home and started researching safety accessories. That’s how I found Brake Free. I saw some reviewers mention that it flashes a lot and could be annoying for other drivers. I decided I don’t care. If they’re annoyed by the light, that means they’re seeing me. But my husband drove behind me a few times and he said it doesn’t light up that often—only when it’s supposed to, when decelerating. I think if you lurch a lot while shifting, you’d probably light up more. Regardless, my husband says he definitely notices the light, even when the light is just steady red and I’m not slowing down. He says I’m far more visible at night. Brake Free works exactly as advertised. Installation was simple and easy. The only thing I don’t like about it is that I forget to turn it off. So I wish it had auto-shutoff if it detects no movement after a certain period of time. It was a little pricey for a little light, but if it really does offer even a fraction of added safety, I think my life is worth it!
