I needed head lights similar to The Friendly Swede, but they don't sell them unless in a pair and I didn't need rear red lights, just the white. I found this product very similar to their lights and decided to give it a try and it wasn't entirely what I was expecting. This is a very bare bones version. Lights of this type should have an internal structure, a plastic casing, followed by a rubber casing to cover the entire thing. This light only has the internal structure, no plastic casing, and a rubber casing; there's exposed wiring just uncovering the lights! If you stick your finger in the wrong direction or forcibly move the casing too hard, you risk damaging the whole light; don't drop it as it can't handle hard physical abuse! The light itself works though, it's bright as their competitor, though making it red on the sides was an odd choice of design. Overall though, the lights works and it's been doing well for me. However, I had to be extra careful whenever I have to replace the batteries, avoid dropping it, and avoid water exposure as it's not waterproof at all. A few well placed drips of water could destroy the exposed circuitry! Keep the lights dry! For lights under $4 though, you get what you paid for.
