Review on 💡 Enhanced Visibility with Serfas Vulcan 130 Lumens Tail Light - TSV-130 by Matthew Baltimore

When this light is on, it's bright and powerful. The problem is that it's incredibly difficult to make it glow. Oftentimes, pressing the power button has no effect at all. It usually takes a few tries before the cumbersome button is pressed properly. Despite this, it is completely impossible to predict which setting will be activated. I've learned to ignore I'll settle for any brightness level or blink pattern just to get this dumb thing to work when I need it.
