LEZYNE Strip Drive Pro Bicycle Tail Light, 300 Lumens, 53H Runtime, USB Rechargeable, Rear Bike Light, Black

Brightness is great and the battery life is also great.

Was at first wary about purchasing such a pricy tail light for my bike, but after reading the reviews, decided I would go for it.Am *very* glad I did.The light is really a little dynamo. About ten different brightness and pattern settings including- 3 steady settings: high, medium and low- 1 *extremely* bright variable-flash setting (kind of like a heartbeat: flash-Flash, flash-FLASH; flash-Flash, flash-FLASH) which is great for visibility in bright daylight- 1 bright variable-flash setting (same heartbeat pattern at one above, just less bright) great for visibility on a grey or overcast day (or for when you don't want to blind motorists with the *extremely* bright setting above- multiple assorted blinking/flashing/chasing combinations and- 1 very economic single-dot slow chasing setting good for a long marathon stretch at night on a quiet country roadCouldn't be more pleased with the brightness, durability and flexibility/ease of use...Good battery life. Easy to charge.The main thing though is its excellent spectrum of choices, from extremely, almost blindingly bright to pleasantly low...for any situation and whatever the situation may require.I can also attach it to the basket of my bike when i am carrying things (best done with body suspended between the metal rods with the strap going around the rods for support)

Perfect for day and night

I’ve had lots of tail lights, this is one of the best. It lives up to all of the claims in the description around brightness, battery life etc. The form factor and dimensions are spot on for aero seat posts and it will work well with a “D” shaped, flat backed seat post with some modifications. The little insert that is supposed to work well for flat backed posts is a puzzling design. I’m an engineer and pretty good wit a wrench and frankly I’m baffled by the design. Like another reviewer I used a rotary sander to sand the “ears” off the back and sand the back flat to a point that doesn’t compromise the case and gives me the angle I want. Once done this works great, the light is much more secure. The second “niggle” is the attachment strap, it works pretty well but is a bit on the flimsy side and I expect it will break after a couple of months of normal use ( I typically ride 5 days/week min.). That shouldn’t be the case, I’ll likely replace it with a more rugged rubber o-ring of the right size to give the proper tension long before that as I don’t want the light coming loose during a ride and getting broken or going missing. So overall the best tail light I’ve seen for aero/D-shaped seat posts but the design does need a bit of work. On a round or oval post it works a champ right out of the box.

Este producto es sencillamente genial y no exagero al decir que puede ser de los mejores en su segmento. El único punto a mejorar es su precio pues es algo elevado.
