EQUIPMENT LIMITATIONS: The approved tail position

light assembly should be mounted vertically and as far aft
on the aircraft as possible, on a thermally conductive
surface

CONTINUED AIRWORTHINESS: The LED tail position
light assembly is designed with 6 LED’s. If any one LED

or cracking.

INSTALLATION PROCEDURES: The following
information is to assist you in installing a Whelen tail
position light.

1. Choose the appropriate model light assembly which
is most applicable to your aircraft.

2. Remove the old light, locate and save the existing
+28VDC lead and (-) ground lead (7101102 &

7101103). Clean and prep ends as required.

3. Use the existing mounting holes and hardware.

4. For model 7101101, secure the existing connector
onto the base of the light assembly. For models
7101102 & 7101103, connect the existing +28 VDC
lead to the white 20 AWG lead on the input cable
assembly (supplied with light assembly). Connect the
existing ground lead to the black 20 AWG wire on the
input cable assembly. If a chassis ground wire exists
on the aircraft, connect it to the chassis ground wire
assembly. Both leads must be connected by FAA
approved techniques using approved hardware.

5. Make sure the existing system is equipped with an
appropriate sized breaker.

6. Remove two #4-40 screws from tail light assembly.
Save these screws.

7. Install the light assembly and insure that all the leads are clear
of any obstructions and ty-wrap as required. Secure light
assembly using approved vibration resistant hardware methods.
Note “Top” marking on the unit.

8. Re-mount the lens and retainer onto the assembly. Attach the
lens and retainer with mounting screws (provided).

9. Check all avionics systems for interference from this installation.

10. When waterproofing the assembly to the aircraft, apply aviation­approved single part silicone (RTV) or equivalent around the
periphery with caution. Do not fill the drain holes at bottom of
unit. RTV should never be used between the rear surface of

the light assembly and its mounting surface.

11. Update aircraft records, complete Form 337 and obtain FAA
