INSTALLATION PROCEDURES: The following
information provides guidelines for the installation of
the Whelen LED PAR Lights listed above. Please refer
to the OEM manual for your aircraft for specific
removal and installation instructions.
1. Place the lighting switch in the OFF position.
2. Inspect the housing, attachment points and
retainer for any signs of abnormal wear or
damage.
3. 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.
4. Place retainer screws in a safe place.
5. Remove the lamp from the holder.
6. 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.
7. 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.
8. While holding the lamp, loosen the screws
holding the attached wires. Remove each wire
from the lamp.

9. 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.
10. 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.
11. 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.
12. 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.
13. Secure the retainer. Care should be taken to
tighten the screw only to the point the retainer
does not turn with hand pressure. Overtightening may stress the polycarbonate lens of
the LED Light.
14. Place the light switch in the ON position and
verify proper operation of the Whelen LED lamp.
15. Update records in accordance with 14CFR
91.407. Determine that the landing or taxi light
characteristics have not been substantially
affected.
