(note: if your helmet has a visor - remove said visor, install said mirror, and reattach said visor.. voila! Do NOT be afraid to bend the mirror shaft to position for your vision!) Try not to bend the wire at the junction of the mirror and wire... it may snap off. Hold the mirror head and bend the wire in the middle. HubBub Helmet Mirror Installation Instructions: 1.
