Abstract: A bicycle safety light positioned on a bike pole including a dome shaped cover, which is translucent and of a color to emit light distinguishable for vehicle safety purposes. The dome is mounted on a removable base adapted to receive a battery case on which is mounted a blinking light bulb and on/off switch. When installed in the base the bulb is housed within the dome shaped cover and the switch is easily accessible to actuate the bulb; batteries are disposed vertically in the battery case which is separately removable. A reducer permits attachment of the cover, batteries and battery case combination to an extender (bike pole) the other end of which is affixed to a mounting bracket to facilitate mounting the safety light on a bicycle, motorcycle or the like. An opening in the reducer permits access to the off/on switch. The dome may be vertically adjustable to change its position with respect to the bulb.
