Excellent helmet. The winter liner comes out easily for replacement with a rain hood or summer sweatband-skull cap. The LED light uses the 2025 battery which replaces easily with jeweler screwdrivers. Online the LED light box is $10, however, I owned 3 LED dog collars that worked until the plastic strip in the collar got too yellow to transmit light. I covered the rear black plastic with Walmart automotive red reflective tape. The top of the visor I covered with white reflective tape.
