Before the gauge panel is re-installed, you will need to set your LED brightness on your
dimmer. Make sure all electical connections are completed and re-connect the negative
battery lead to your battery. To set the dimmer, be sure that the dimmer is wired to the
original light circuit (red to gray, black to black). It may be helpful to set your dimmer in a
dark garage.

Place the provided acrylic wiper cover plate over the light box assembly and turn on the
truck headlights. If the wiper LED does not illuminate
, hold the middle “Speed/
☼
/Power”
button until the wiper LED turns on. Press the “Light/
☀
” button to activate static mode. In
static mode, the middle “Speed/
☼
/Power” button will make the bulb dimmer. The
“Light/
☀
” button will make the bulb brighter (Figure
15). There are 10 different settings to
match the brightness to your other gauges.
NOTE:
If the LED does not illuminate or respond
to button presses, you may have one of the components wired backwards. Simply double
check your wiring and fix as needed. Also ensure that the small LED wires are not crushed,
twisted, or bound up.

The “Mode” button enters dynamic mode. This will cause the wiper LED to flash or flicker.
This function is likely not desired for your wiper LED. If you accidently enter this mode, hit
“Light/
☀
”
. To confirm the correct settings, leave the wiper LED on and turn the truck lights
off and then back on. The wiper LED should now turn on with the truck lights and remember
the last setting.

Once you set the desired brightness, the dimmer will not require any further adjustment and
may be tucked behind the dash with the switch wiring (Figure 16). Once you have the LED
brightness set, disconnect the negative battery lead from the battery.
NOTE:
Take care in
tucking the wires behind the dash. Ensure that the small LED wires are not crushed, twisted,
or bound up as this could prevent the LED from working.
