Hi guys. Well one time or another over the years, I must have hit a rather large bump and grounded out my front bumper, therefore cracking both fog light lenses. I was about to start getting a bunch of parts for my car, and now I'm trying to find out:

Do I have to replace the entire fog light assembly? Is it possible to replace JUST the front plastic lens? I seem to not be able to find just a lens, but only the whole unit. Volvo wants $160 EACH, but I know I can get them cheaper online. But I would still rather only replace the lenses. Any helps greatly appreciated, thanks.
