What's your budget? If you want to go more on the expensive side, Outbound Lighting has a special GoPro adapter for mounting the lamp hanging. Lupine also offers an GoPro adapter for their SL(-F) series of lights, and both lights are usally mounted with a quick release out the front of your handle bar. Otherwise, there are some versions of Lezyne lights that have threads on top of the lamp housing where a gopro adapter can be attached.
