Push the lamp unit forward, then pry it out of the fender using either your fingers, or a small piece of plastic or wood (to avoid scratching the paint). I used a small flat blade screwdriver to gently pry it out from the right side (closest to the wheel)… Here is a link to a handy side marker lights DIY in our members forum.
Most Volvo’s do not already have a wiring harness in the fender for turn signal repeaters. Some 850‘s do (possibly other later models too). For you 240 and 740/760 & 900 owners, you will have to wire it yourself.
On my 240 and 740, I removed the wheel first. I then removed the plastic inner fender liner, a very simple job with only a few screws to remove. Then I simply ran two wires forward to the front turn signal.
You might need to drill a small hole in the inner metal fender if you can’t find a place to pass the wire through to the engine bay. If you drill a hole in metal it’s a good idea to install a rubber grommet to prevent the wires from chaffing against the metal.
It does not matter which wire on the side marker goes to the 12v hot wire for your turn signal. On most Volvos I’ve seen, one side had a green wire and the other side a blue wire. The other side marker wire goes to the turn signal’s black ground wire or simply connect it to a good chassis ground. Simple plastic crimp-on wire splicers work fine for splicing into your existing wires. I use an inexpensive 12 volt circuit tester to verify the wires I use. This eliminates guesswork. The type that uses a sharp point to probe a wire is best for this job.
MVS Forums user David J asked:
I am unsure how to access the side marker lights in the front bumper assembly to replace the “position light”. These are the small, rectangular, flat lights – not the ones which work in concert with the turn signals. At any rate, short of removing the wheel-well skirt, I can’t figure out how to get in there to replace the bulb. Can someone detail how to access these? There are no visible “pops” or “release points” that I can see, and the light itself is part of the trim that runs ’round the car. I don’t want to pay an hour’s labor to replace a bulb, but neither to I want to bugger this car (it’s still cherry at nearly 100K, to all appearances).

the lens will pop out from one side.

Once it’s out, turn the bulb holder counterclockwise to pull out the socket.
Our USDM versions use the 3W W2, 1×9,5d wedge bulb.
