Genuine CatEye Rear Light Spares. This adaptor allows most CatEye rear lights to be mounted on to a standard rear carrier light mount. It is recommended that you fix with a locking screw for theft prevention. Please pull out while pressing the lever when removing. Ensure the light is firmly seated in its bracket before traveling and that the light emission is not blocked by luggage. Light detachment and switch operation should be done when the bike is stopped.
