Review on KRYPTONITE Comet F100 & R100 Bike Light Set: Premium LED Headlight and Back Lights with Long Life Lithium Battery by Ryan Olsen

Package arrived, 1 of 2 devices does not work due to defective/dirty/leaking battery. ONLY spare batteries required. Note. The product description fails to mention two (2) important features. Product diameter is much smaller than expected! Also, the red and white brackets are not identical. The red one has a beveled rubber base while the white one has a flat one. This hidden fact is obviously intended for a very specific bike mount but complicates other possible uses such as: B. on a car bike rack where a flat mount is desired. invisible.
