My Lupine lights let me see and be seen from ahead, but it’s a tail light that makes drivers pay attention from behind.
I just received the DiNotte 300R LED taillight that I ordered a few days ago.
Weight: 148.5 grams
Clamp weight: 10g - 17g (depending on mount)
The Dinotte 300R ships with a whole bag of mounting clamps, so the buyer is pretty much assured of a fit for any bike, and with different bikes, I should be able to install a clamp on several of my bikes, so that I can clip the light on and off.
The Dinotte 300R is very solidly built.
Brightness is nothing short of astonishing, this is the brightest tail light I have yet seen— very impressive. My impression is that in full sunlight it will still be highly visible, but in shade or at dusk or at night, it should be stunningly bright.
Runtime varies depending on setting, but the slow-flash mode runs about 36 hours, whereas continuous-on runs about 4 hours. I see no need for continuous-on, slow-flash looks to be one of the best choices.
This tail light is going onto my bikes for riding; as the year wanes towards the winter solstice, daylight is shorter and dimmer— a tail light is prudent, just like a daytime running light.
