Installation:

1. Remove the existing 400 series lighthead and gasket from the mounting surface.

2. Mark the M4 flange mounting hole locations onto the

mounting surface either by using the flange as a
template or the measurements shown.

3. Drill four 1/4 inch mounting holes and insert the

four supplied #8 round hole grommets.

4. Insert the two #8 square grommets

into the flange and secure the
lighthead to the flange with
two #8 X 1” sheet metal
screws.

NOTE: Due to the mounting hole locations
for the M Series and the variety of lighthead
styles which may be replaced, cutting or
drilling may be required for the screws

going into the square grommets.

5. Secure the Flange and lighthead to the vehicle

with the 4 supplied #8 X 1” sheet metal screws
and round grommets you installed in step 3.

6. Extend the wires to your power source and

connect as shown in the lighthead manual
