Yes, you have halogen reflectors, making putting an LED in them even more of a bad proposition.
1) Make sure the lamps are aimed properly. I've seen so many misaligned vehicles (lights aimed too low).
2) You can buy Sliverstar Ultras and the like. You'll see a brighter, whiter light. Of course the trade off is bulb life, but that's expected with overdriven bulbs.
3) Look to do an HID headlamp assembly retrofit. It's not very difficult, but will need a DICE unit and a laptop to use VDASH to change the lamps. I forget what else could be involved, as I've only read about it here and have not done it myself. You of course will have to find a set of good assemblies somewhere or buy new from Volvo.
4) Last resort, you could always have a retrofitter install some aftermarket HID projectors in your housings. You will need to send your housings though, so that proposition is always difficult. I used to do a lot of retrofitting in the past, but I did it on easier to open assemblies (those sealed with butyl rubber). The Volvo housings have a much more permanent elastomer (some call it Permaseal) that is a bit beyond my pay grade (more so my tools). The pros deal with it better though. You can get much, much better output with some of the aftermarket HID projectors than the Valeo HID projectors in our cars, and miles better than any standard halogen filament reflector/projector.
Last point I generally like to make to those who feel the housings don't do a good service: Get on a road at night in a dark area and turn your headlamps off. You'll see how much the headlamps actually do for you.
