Form No.14142 (091307)
POSITION LIGHT:
Operational Voltage:. . . . . . . . . . 14/28 VDC (nominal)
Input Current: . . . . . . . . . . . . . . . 0.5 / 0.25 Amps
EQUIPMENT LIMITATIONS: An approved lighting
system consists of two lights, one located on each
wingtip. The baseplate must be mounted parallel to the
vertical and horizontal centerlines of the aircraft to project
the patterns properly.
CONTINUED AIRWORTHINESS: The 90377 series
LED wingtip position light assembly is designed with 3
forward LED’s and two aft LED’s. If any one LED fails,
the unit must be repaired or replaced. Inspect the lens.
Replace if there is excessive scratching, discoloration or
cracking.
INSTALLATION PROCEDURES: The following
information is to assist in the installation of a Whelen
90377 Light System.
1.
Choose the appropriate 90377( ) series
replacement light assembly.
2. The installation procedure described in the following
text will be confined to a single light installation, but
is identical for multiple light installations.
3. Remove the old light, locate and save the existing
+VDC lead and (-) ground lead. Clean and prep
ends as required.
4. Make sure the existing system is equipped with an
appropriate sized breaker. Connect the existing
+14/28 VDC lead to the POSITIVE wire on the input
cable assembly (supplied with the light assembly).
Connect the existing ground lead to the GROUND
wire on the input cable assembly or use the
supplied connector as shown in the illustrations.
Both leads must be connected by an approved FAA
connection. Insure that the wire leads clear of any
obstructions and ty-wrap as required.
5. Remove the shroud from the light assembly.
6. Position the base of the new light assembly onto the mounting
surface. Insert three (3) #6-32 pan head screws into the
mounting hole and tighten firmly. Reinstall the lens so that the
two notches are positioned under the shroud, with each notch
equadistant to the centerline.
7. Check all avionics systems for interference from the
installation.
8. A flight check should be performed by a properly certified
pilot.
9. Update aircraft records, complete Form 337 and obtain FAA
field approval for installation, as required.
