Rain is what sorted these sets for us, and the Cuvccn came out of it best. It carries an IPX6 rating — one of three sets here built to take a jet of water rather than a splash — and that's the difference between a light that shrugs off a downpour and one that ends the ride with water sitting behind the USB cover. Both halves charge over USB through a silicone plug, and that plug is the part that decides whether the rating holds up in practice.
Output is a genuine 400 lumens, spread wide by two main LEDs ringed with 19 auxiliaries, so the beam picks out a pothole at the edge of your line rather than punching one bright spot down the middle. Twelve settings across the pair cover steady, flashing and pulsing at both ends, so there's a mode for a lit street and another for the unlit mile at the end of it. What we kept coming back to, though, is the pair of independent switches: the front and rear each have their own button, which means a steady beam up front and a flash behind without cycling through the front's modes to get there.
The strap is the one thing to check before you order. It needs a decent stretch to seat properly, and on a heavily padded or oversized bar it can come up short; on the bars most bikes come with, it goes on in seconds and releases just as fast when you want to charge indoors or lock the bike up.
Bottom line: The set we recommend first: a wide 400-lumen beam, IPX6 water protection that leads this group, and separate front and rear switches for less than the premium picks here.
