Bookman's rechargeable Block lights look really handy for getting you noticed by other road users, whether that's on urban streets at night, or when you're out and about in daylight.
Each light is tiny, measuring just 35 x 23 x 14mm and weighing 12g, so you can easily tuck them away in a pocket until required.
You can run the front light at either full power – 50 lumens – or at 25%, and you can also choose between steady and blinking modes.
The runtime in steady mode at full power is 1:30 hours, rising to 25 hours at the lower setting in blinking mode.
The rear light is 18 lumens at full power, and it'll run for about 1:30 hours in steady mode. Again, you can switch to 25% power and/or blinking mode, and the maximum runtime (low power, blinking) is 25 hours.
The Bookman lights are about as simple as you can imagine: one LED per light with a stretchy band keeping each one in place on your handlebar or seatpost. A curved rubber pad on one side of the light helps hold it there.
The lights are water resistant and the lithium ion battery will recharge from flat in two hours via the micro-USB cable that's included in the pack.
There's not enough power here for showing the way on unlit roads but the Block lights can help get you noticed on urban streets, especially as a supplementary light in flashing mode, and they're a useful back-up option if your main lights run out of juice halfway home, for example.
They're also good daytime running lights, surprisingly noticeable even on a bright day.
