From The Retrofit Source. Originally meant for my c30 however the light output in projector housings is actually less than halogen. Lucky for me the xc60 is also H11. The best part is I did not have the cut out the back of the housing to accommodate the fan housing. And, I don't get a bulb out warning like I did on the c30. Haven't driven at night yet but expectations are high. 2nd pic is halogen on the passenger side and led on the driver side.
