Elliptical Halo Shield Instructions
First remove any factory halo shield.
Then stretch the base of the elliptical shield over the head of your light. On Wicked Scanpro models you must get the new halo back past the knurled section of the light or it will slip off easily. The shield should now be rotated until it is horizontal at the focus setting you choose to scan with on your light. The beam pattern will be wide and not very high only putting light where you need it.
