Like MrNabisco says, you can restore the factory plastic U.S. DOT lenses.
The U.S. DOT lenses for 240 1986+ cast an inefficient beam. Yet do okay on all weather when motring the posted speed limits. Still, the glass e-codes get raves for casting a better beam using the same or high lumen bulbs. You can use LED bulbs.
There is on example where someone converted their 1992 240 to the dual round beams of old.
It takes some time and prep, yet they can cast a beam ahead of you.
If you pull from underneath of the the center corner front of the clear lens and it pulls up from the assembly, you have to either repair or replace it. As water intrudes, a hot head lamp bulb can explode.
You'll need to remove the turn signal / headlamp assembly.
Try to search here for using like oven cleaner or toothpaste to debride the interior vertical fluted surface of the lens. I've written and done the procedure maybe half dozen times.
The factory adhesive joining and sealing the clear lens and reflector body fails on all 240s with the plastic lens U.S. DOT lenses. It also happens on some iterations of glass lenses on other, later RWD Volvos.
Dissemble, clean the interior. Some will use oven cleaner and a scrub brush on the interior side. The water intrusion and hot bulb makes for a fogged lens. In some instances, the water intrusion can cause the lens to explode, ruining both the reflector and the lens interior.
Scrap away all the crusty grey adhesive on both sides - the protruding edge on the lens and the groove on the reflector body edge. Use some sand paper to rough up the interface on both sides.
You can *gently* clean the reflector with a soft cloth and running water. Simple green or dish detergent works well.
There is a reflective aluminum strip adhere to the bottom of the lens. It may have some green algae or other nasty stuff around it. A spray of weak bleach solution
I've had good luck with GOOP brand adhesive sealant. You want one of the two RV resist type. Use the RV or Marine versions of GOOP.
I use newspaper to protect the lens from tape adhesive and use packing tap to adhere, tightly, the clean and polished lens to the reflector body. Put a fan opn it, with the lend facing down, so the fan blows over the head lamp bulb hole to accelerate the adhesive to curing (outgassing). Put out doors or in a ventilated area.
Other folks here may have better adhesive and process suggestions.
You may want to clean the corner marker lamps and lens interiors. These get dirty.
Reassemble when the adhesive has cured, About two or three days. If you get a spare set from the junkyard, you can repair these and drop them in.
As for the tail lights, well, that's an approach that is complicated, a bit. You can suffer the tail lights, restore them, or buy new Volvo OEM or after market. As I like to cite my own artwork:
Filled with water. Lens coated inside and out with GOOP RV adhesive. Remains clear in sunlight exposure. I drilled hole to allow it to drain.
I mean to restore the many tail light sets I have for sedan. All six panel post 1981 or 1982 wrap around tail lights and some for wagon. I have the two or three three different flexi silly circuit boards. It's a pain to deal with.
240 six panel wrap around sedan tail lights sort of suck. About one every year or two I'll have to rapidly restore one (usually North America driver side) as the flex circuit board or the water intrusion is that bad. Water can intrude around the foamy gasket or through crack in the welds where the black reflector body is welded (annealed?) using adhesive to the lens. The white lenses tend to fall out, and you can check ahead of time if the adhesive fails by tugging on it.
See your owner manual. On the outside, bottom row of lens, the outer lens hosts a dual circuit bulb (see your owner manual). The white bulb holder goes to the lower outermost North American passenger side, and the black bulb holder to the lower outermost driver side. Many will incorrectly install these bulbs, or stuff tail lights from earlier Volvos with the single filament brake light (I'm not getting into bulb models, see your owner manual), leaving a bulb on with the parking lights / headlights on, causing the red lens to distort from the constant incandescent bulb heat (yet we have LED bulbs now! Coool.)
You may want to see what salvage yard near may have 240s. Else, buy new as you can afford.
To drill down into more detail will take more time. That may be later tomorrow sometime if you need such info. Try the search feature as the info is in here somewheres.
cheers,
Eggnog Season Boyeeeeeeeee.
