■ FIGURE 5. Taillight
Schematic.
Now you can mount the eye bolts. Secure the nuts with
nail polish. The box I used is water resistant. It should do
fine in rain, snow, and mud. However, I would not
submerge the unit in water (e.g., a boat trailer). See “Hints
and Tips” on the N&V website for a submergible unit.
Add two D batteries to each battery holder and
secure the lids. You are now in business! When you turn
on the switch, the center LED will light for about one
second indicating that you have battery power.
Testing the Units
Plug the transmitter into the trailer power connector.
Bring both units into the cab and turn on. Turn on the key
and step on the brake; both unit’s inner ring should light.
Turn on the right turn signal; the right taillight should flash.
Mark the box on the back with an “R.” Turn on the left
turn signal; the left taillight should flash. Mark the box on
the back with an “L.” Turn on the headlights; both outer
rings should light.
Using It
You can mount the taillights using small bungee cords
or hang them upside down from the bottom eye bolt. Make
sure the taillights are on their appropriate side. Plug the
transmitter in the trailer connector. For best reception, make
sure the transmitter antenna and the receiver antennas are
in the same plane. ALWAYS TEST THE UNITS BEFORE
TRAVELING. Happy trails (and towing!) to you. NV
