INSTALLATION PROCEDURES: The following information
provides guidelines for the installation of the WAT LED PAR
Lights listed above. Please refer to the OEM manual for
your
aircraft
for
specific
instructions.
1.
Choose the appropriate replacement light assembly.
Note: It is not required to change all PAR lights or Taxi
lights to the new LED PAR lights.
2.
Place the lighting switch in the OFF position.
3.
Inspect the housing, attachment points and retainer for
any signs of abnormal wear or damage.
4.
Loosen or remove the hardware holding the lamp in
place. Take steps to ensure the retainer doesn't fall
from the lamp assembly before it is ready to be
removed.
5.
Place retainer screws in a safe place.
6.
Remove the lamp from the holder.
7.
Note there are two wires connected to the (existing)
lamp. Using a multi-meter, identify the negative wire by
measuring continuity to ground. Place a piece of black
electrical tape around the wire identified as ground.
This is your negative lead.
8.
Identify the positive wire as the remaining wire lead.
The LED light assembly is polarity sensitive, however
you will not damage the unit by reversing the polarity.
9.
While holding the lamp, loosen the screws holding the
attached wires. Remove each wire from the lamp.

10. Secure the LED Light, note the terminal markings for
positive and negative, attach the negative marked wire
to the negative side terminal post of the LED Light.
11. Attach the positive wire to the positive side terminal
post. Remove tape or temporary placard which
identified the polarity of the wiring inside the housing.
12. If required, install the rubber gasket included with your
new LED Light around the LED Light assembly. A light
application of a common hand soap on the rubber may
aid in its fit into the light housing.
13. Place the LED light into the housing ensuring the key
(of the assembly) matches the key of the housing.
Proper orientation of the lamp is necessary for beam
orientation to be left and right of centerline while in
operation. For a Taxi light, the 'lines' of the inner optic
should be orientated vertically to produce a horizontal
light beam.
14. Secure the retainer. Care should be taken to tighten the
screw only to the point the retainer does not turn with
hand pressure. Over-tightening may stress the
polycarbonate lens of the LED Light.
15. Place the light switch in the ON position and verify
proper operation of the WAT LED lamp.
16. Determine that the Landing or Taxi light characteristics
have not been substantially affected, per 14CFR
23.1383.
17. If required, update aircraft records utilizing FAA Field
Approval (Form 337) or equivalent.
