This product allows you to cover the 12 Volt socket of your Volvo if you lost the original cap, or if you just want to replace it with something smaller and neater. It totally looks like a stock accessory and fits almost flush with the surface around it, especially compared to the bulky one that came from factory. Even if thinner, it's still really easy to unplug thanks to the finger grips inspired by the Ford factory blank plug.
The socket cover is compatible with the following Volvos: C30, C70, S40, S60, S80, V50, V70, V70 XC, XC60, XC70, XC90 of different years. Shortly, it will fit snug in your vehicle if your original cap looks like this, but you can still check a full compatibility list here.
