Review on 🚦 One-Unit Solution: Introducing the New Version of Brake Pulse Flasher Stop-Alert for LED Tail Light & Stop Bulbs in Cars, Trucks, Motorcycles by Lorenzo Wood

Revainrating 3 out of 5

I love blinking, but I'm not happy with the delay

I noticed a slight delay when turning on the module (the brake worked) before the blinking started, so I checked the input and Output viewed on the oscilloscope. See attached screenshot of the area. The blue curve is the input voltage of the module and the yellow curve is the output voltage of the module (brake light control). The module causes a delay of approx. 1/5 second (195 ms) between the braking process and the switching on of the brake light. When I measured this I wrestled a lot with myself about installing the module on my bike as I really liked the flashing, but I really hated that long delay between braking and the brake lights turning on. In the end I decided to install the module. For reference, at 60 mph it travels about 18 feet in 1/5 second. I'm hoping the benefit of the blinker of actually getting someone's attention outweighs the car's 18 feet behind me at 60 mph before the brake lights even come on. As an electrical engineer who has been designing electronic products for about 35 years, I know full well that I could design a module like this that would likely have a delay of less than a millisecond between the brake being applied and the brake light being on. Perhaps my design could not have been made in China at a price that would have sold it for a $9.95 profit. :-/

Pros
  • Lots of positive emotions
Cons
  • No power
