4.Heat the soldering iron in six minutes. Solder one end of an electrically conductive pin to the center contact on the underside of the laser Assembly. Let the solder cool for two minutes. Solder one end of the second conductive pins to the connector to the right of the middle connector on the bottom of the Laser Assembly. Let the solder cool for two minutes.
5.Pick up the red laser diode of the base of the two pins protruding from the bottom using the tweezers.
6.Insert the longer of the two pins protruding from the bottom of the red laser diode in the center hole top of the laser congregation.
7.Put shorter pin that sticks out from the bottom of the red laser diode in the hole to the right of the hole in the middle.
- Press the red laser diode to fully engage the two pins in the holes. Remove the tweezers.

- Drop some solder on the center hole. Let the solder cool for a minute.
- Solder end of the second conductive pins located on the bottom of the laser assembly to the connector orbiting hole in the ball assembly. Let the solder cool for a minute.
- Carefully align the laser parish so it is inside the flashlight with red laser diode outward.
- Turn the locking ring back to the front of the flashlight. Screw the reflector back to front.
- Insert the batteries in the battery compartment on the back end of the flashlight. Screw the battery cover back in.
