the inner bulb cover by turning it counter-clockwise about 1/4 circle.
2> Volvo's directions say do the same
as above to the bulb itself, this won't work unless you're Hulk. Get
small torque screwdriver and loosen the 3 screws that are holding up the
plastic ring (no need to remove them completely). After this turn bulb
counter-clockwise 1/4 circle and bulb comes off.
3> Remove the power cord and insert the new bulb and
do the exact opposite to 2 & 1.
1> Turn the black housing behind the fog light 1/4 turn
counter-clockwise, this should expose the bulb.
2> Remove the ground wire.
3> There's a small metal clip holding the
bulb in it's place, it's very easy to confuse from which side you should
open it. On the other end there's like 2 small extensions, grab those
and push them together at the same time as you push towards the bulb
slightly, this should open the clip and you can remove the bulb. Take
notice how it is in the housing (small round cut should be pointing up).
4> Remove the power
cord and insert the new bulb and do the exact opposite to 3, 2 & 1.
