Knog Frog front and rear lights

Weighing little more than a handful of paper-clips Knog’s Frog’s are surprisingly bright miniature LEDs, ideal for contingencies and complementing ultra compact Li-on lighting systems but fall dangerously close to the trap of being style over substance-especially compared with their Bullfrog siblings.

Encased in medical grade silicone and available in a choice of twelve colours to complement or contrast your bike’s livery, these stretch fit securely around most handlebar and seatpost diameters-or if you prefer, fork legs and seat-tubes. Minute dimensions and clever styling prevents them spoiling a race bikes’ clean lines and they’re a delight to use even wearing winter weight training gloves thanks to positive switches. However, despite claimed visibility of up to 600metres, single beams lack the presence of larger designs and the latest generation of micro lights.

Build quality is definitely up to the firm’s usual standards-our pumpkin coloured rear unit came unexpectedly adrift at speed, taking quite a knock as it hit the asphalt but mercifully, bulb and internals remained completely unscathed. This is largely attributable to the silicone casings, which, while not waterproof in the literal sense, shouldn’t succumb to the elements anytime soon. Burn times are pretty faithful to manufacturer claims, our test pair managing 77 hours in constant and 156 flashing modes respectively.

Ultimately, style conscious riders wanting beautifully designed emergency micro-lights for late summer/autumn evening ride contingencies won’t be disappointed but others within the Knog range and elsewhere represent better value.

Verdict

Very stylish, pretty lights but form outweighs function.
