Lighten our darkness - A Volvo Part for a Volvo - it fits perfectly & works well
Pros:
(1) It's a fog light so it lights up where you're going in fog
(2) It performs exactly as you would expect
(3) It's for a Volvo S80 so it's well made & fits
(4) Even if your S80 didn't come with fog lights it comes with all the wiring in place so it's a case of just plug it in.
Cons:
(1) If your S80 didn't come with fog lights the dashboard switch is covered with a blanking cap; the cap can be removed (with great care) and the switch is underneath the cap, although it won't have a nice cover with a little fog light symbol on it. Ah... sometimes life's just hard...
(2) It fits below the bumper this means you have to lie on your back & stick your head under the car to fit it, dirt might fall into your mouth and/or eyes so keep your mouth closed & use protective eyewear if this bothers you.
