Replacing the Impaxx (VSLR1-IPX only)

The Impaxx is replaceable in one piece.

Tool required: 

 

T20 Torx driver
3/8" nut driver
7/16" socket or nut driver

Removing the Impaxx

To remove the Impaxx:

1.

   Disconnect all power to the light assembly at the battery. 

2.

   See Figure 6 on page 10. Use a 7/16" socket or nut driver to remove the three 1/4"-20 elastic stop 

nuts securing the unit to the vehicle. Lift and invert the unit.

3.

  Use a T20 Torx driver to loosen the four #10-32 Torx flathead screws and remove the base plate.

4.

  Lift the Impaxx and bracket assembly from the unit and unplug the electrical connectors from the 

Impaxx.

5.

   With the 3/8" nut driver, remove the two #10-32 nuts securing the Impaxx to the bracket.

6.

  Inspect the gasket on the Impaxx to insure it is not torn, brittle, or damaged. Replace it if 

necessary. 

Installing an Impaxx 

To reinstall an Impaxx:

1. 

Install the gasket on the Impaxx  The wider end of the gasket goes down (touches the base plate).

2.

  Install the bracket and secure with the #10-32 nuts.

3.

  Reconnect the electrical connectors to the Impaxx (red to red, black to black).

4.

  Place the Impaxx assembly in the correct location in the unit and install the base plate,

5.

  Insert the #10-32 Torx flathead screws. To prevent cross-threading, back the screw 

counterclockwise until you hear the click of the threads engaging, then tighten the screw. 

6.

  Position the light over the mounting holes and route the cable through the grommet. For the 

VSLR1-IPX, allow 10" to 18" of slack in the cable under the roof so the unit can be removed 

if the Impaxx needs replacement. To prevent water leakage, apply a silicone sealing compound 

around the cable and grommet where they pass through the mounting surface. 

7.

  Secure the unit to the mounting surface with the three 1/4"-20 elastic stop nuts. 

8.

  Reconnect power to the unit.
