Maintenance

Lens Cleaning

Use plain water and a soft cloth, or Code 3® lens polish and a

very soft paper towel or facial tissue. Plastic scratches easily, as

a result, cleaning is recommended only when necessary (about

every six months). Do not subject the lenses to car washes that

use brushes, as these will scratch the lenses.

Lens Removal

First, disengage the lens clips (4 per lens) as shown in

Figure

. Finally, insert a screwdriver into the small slot in the lens clip

pocket for the lens edge, and twist the screwdriver to lift the lens.

Lamp Replacement

Remove the lens as outlined above. Next, inspect the lamp and

refer below to replace the lamp.

Note: Make sure lamp is cool before attempting to change it.

Also, when installing a new lamp, be sure not to touch the glass

with fingers. If contact is made, clean the glass with a soft cloth

after inspection.

replacement. Remove the lamp assembly by removing the appro-

priate fasteners, remove fasteners sandwiching MR-11 in bracket,

H-3 55w Style Assembly

Caution: Extreme care must be taken when removing

halogen lamps to prevent burns and bursting of glass.

Step 2 With the lighthead assembly placed on a work surface with the lighthead up, remove the four screws that attach the lighthead to the lightbar

mounting bracket (see Figure 4). It is not necessary to remove the heat shield.

Step 3 Remove the two lamp mounting screws with a Phillips screwdriver (see Figure 5) and remove the lamp.

Step 4 Replace the lamp and reinstall the two lamp mounting screws making sure to replace and attach the black ground wire with one of the lamp

mounting screws.

Note: Replacement H-3 55 watt lamps are available from Code 3®, Inc. or you may obtain the lamp from your local auto parts store. If you

you obtain the lamp from your local auto parts store, it may be necessary to change the terminal on the power wire to mate with the new

lamp's terminal (depending on the lamp manufacturer). This terminal (fully insulated 1/4" female quickslide) is also available at your local

auto parts or hardware store.

Step 6 Reinstall the 55w lighthead to the lightbar mounting bracket with the four screws previously removed.

Step 7 Remount the 55w lighthead assembly in the lightbar and reconnect the wiring.

Use the same procedure to replace the lamp for the 55w Dual Lighthead assembly (see Figure 6) .
