    The SDU-5/E strobe light was issued with various aircrew survival vests and life preservers. It was waterproof and produced an intermittent flash of light visible for beyond five miles.  This strobe was used for Special Forces Operational Detachments during night HALO jump operations.  Army and Special Forces recon units also used the SDU-5/E at night to mark their position on the ground to circling planes. In such cases the strobe was placed inside the barrel of an M79 grenade launcher so that only those above the end of the barrel would see the flash, thus preventing the enemy from seeing the exact position of the team.

    These were used in our NIGHT HALO jumps and we have opted for Mantas and Fire Fly's so these are up for sale.

    Please note!  Do not over tighten, place two CR123A batteries +down towards the cap in the battery compartment and slowly tighten the cap. Once snug press the switch to confirm contact. If strobe does not fire, slightly tighten and test again until strobe fires.
