  Q: How to remove and install a fog light lens, and How to ensure proper operation and aiming on Volvo 940?

  A:

  To remove the fog lamp lens, use a small pry tool, then rotate the light bulb counterclockwise to remove it from the fog light housing and pull it out. For installation, insert the new bulb in the housing and turn it clockwise to lock it, followed by snapping the lens back on the fog lamp assembly. Test the lights to be sure they operate correctly and if you have any problems with the lights, they should be checked for a bad light bulb, dirty socket, faulty wiring or a blown fuse. Before installing aftermarket auxiliary lights, check whether they are legal to use on the road, as they should have a DOT approval number and should also be legal to use in that area. Disconnect the negative battery cable and unpack the light kit and select a suitable location for the lights, preferably underneath the bumper for fog lights and on top for driving lights. Drill the necessary holes for mounting and secure the lights with the included hardware and install the relay in an immovable area of the engine compartment with terminals facing down to prevent water from getting in. Connect a wire from the ground connection of the relay to a good ground source and then connect wires from the light to the fog/driving lamps and from the ignition to the light switch. Install the light switch in an appropriate position and attach it to a constant power source as per the local laws. Finally, wire with an inline fuse from the power terminal on the relay to the battery, reconnect the negative battery cable and turn on the lights to adjust the pattern if necessary. To aim, put the vehicle on level ground facing a flat wall about 25 feet away and turn on the lights, and loosen the mounting hardware to adjust the beam so that the distance between the lights is horizontal and the fog lights are 4 inches lower than the center of the lamp lens and the driving lights are aligned with the center of the lenses. Tighten the hardware and test the lights for proper functioning with an even pattern.
