20 mm searchlight
Order No. 566720
The searchlight swivels and tilts, and its articulation can be controlled by
mini-servos. The LED must be fitted with a series resistor!
Bend the sides of part 1 through 90° as shown. Insert the sides 2 and solder
the box joints on the inside. Pass the tube 4 through the box and the top
cover 3. Align the cover carefully before soldering it to the box from the
underside.
Solder the 1.5 mm brass rod 7 in the holes in the bracket arms 6 and 8, then
cut down the rods to a maximum length of 2 mm on the side with the etched-
in grooves. Sand or file it back flush with the bracket arms 6 and 8. Solder
the tubes 4 and 5 in the centre of parts 6 and 8. The tubes should project at
the top, but by no more than 1 mm. Glue the two tilt bushes 10 centrally to
the searchlight housing 9 using cyano. Drill 1.5 mm holes through the plastic
tube, then remove the drilling burr on the inside.
Fit the LED 14 in the reflector 15. Cut down the terminal pins attached to the
LED to a length of 7 - 8 mm, then solder the wires to the LED terminals, and
insulate the soldered joints. Bend the wires over at the reflector. Drill a 2 mm
Ø hole in the centre of the bottom of the searchlight housing for the wires to
pass through; the hole should be located behind the bracket 6. Pass the
cables through the hole and insert the reflector. Peel off the inner protective
film from the lens 16, and press the lens into place.
Complete the rear cover 11 by fitting the handles 12. Insert the rear cover in
the searchlight, and glue the latches 13 to the cover and the searchlight.
Bend the swivel and tilt brackets 6 / 8 through about 45° in the direction of
the grooves. Slide the tubes into each other, and allow the shafts to snap
into the tilt bushes 10. It should now be possible to tilt the searchlight by
moving the inner tube. Fit the tube through the box.
The searchlight can now be painted. Remove the protective film from the
lamp lens when the paint is dry. You will find two etched 1.0 mm holes on
either side of the rear cover 11 which are intended to help when replacing
the LED. If a repair is needed, drill out the holes and push a length of wire
through them to push out the reflector and lens.
