INSTALLATION OF MODEL A612 with an A610 Flash Tube
A612 glass lens and A610 flash tube are used for installing wing tip strobes in single engine Cessna's
1972 and later. The existing position light retainer is modified to accommodate the lens, and the flash
tube is mounted directly behind. The unique magnifying design of the A612 lens increases the light
intensity by two to three times in the horizontal plane. These items may be used for custom instal-
lations or as spare parts for existing light assemblies. The A612 lens is available in Aviation Red and
an RFI coated version. Lenses meet material requirements of MIL-C-7989B Class B.

Installation of A610 and A612
Figure 38d
1. Remove the position light
lens retainer being careful
not to drop the Red or the
Green lens.
2. Establish a center line on the Cessna lens retainer, referencing to the
lens retainer center mounting screw, and position light base plate rear
mounting screw.
3. Scribe the A612 lens profile as shown in illustration (Figure 40c, left),
the object being to have the strobe light centered over the position light
base plate.
4. Trim or fit an opening to the scribe line to fit the A612 lens. Due to the
uneven surface of the Cessna lens retainer, the A612 will contact only
the front and rear radius.
5. Place the sponge rubber pad supplied under the A610 flash tube to firm
the assembly. RTV is recommended to secure lens in the modified
retainer.
6. The flash tube interconnecting cable is routed through square holes in
the rear bulkhead of the position light area.
7. Install the modified position light lens retainer, A610 flash tube and
A612 lens, using original hardware.
