Default Location of headlight ballasts on a 2004 XC70 with xenon HID lights

My friend has a 2004 Volvo XC 70 AWD with xenon HID headlights. About 6 months ago the drivers side headlight (lowbeam) went out and after replacing the D2R bulb everything was fine. Then a month later the passenger side bulb went out but worked fine after the bulb was replaced.
Now the passenger sider low beam failure light has come on in the message center AND I note that the high beam also does NOT come on.
I have tried switching bulbs but I can't get the right side lowbeam or highbeam to work. Having searched the forums I read about the possibility of it being either the ballasts or the actual wiring harness. I read that I can swap the ballasts and if then the left headlight goes out then I can be pretty sure that the ballast is bad. My question is where are the ballasts? I see a plastic box located in the engine compartment behind the right headlight assembly which has two silver boxes in them, one a Volvo part and one a Bosch. Are these the ballasts (see attached photo)?

Wish can help you.

I got my kit from manyadeal.com
I got the 4300K color H11 55W kit (most closely resembles stock Volvo HID color).
I got their old Analog 55W kit--and all's well. No BOW.
Must say, that the beam pattern is not great, but there's a lot of light on the road.
Despite the potential for glare, I've never been flashed.

good luck !!!

On my 2006 V70, the ballast is on the bottom of the headlight assembly. To get the headlight assembly out on the V70, remove the 2 screws in the wheel well, 4 plastic buttons on the bottom of the bumper cover and 6 buttons in the engine compartment. Pop off the bumper cover, remove 2 bolts for the plastic bumper and drop it to the ground (this part is in the way of getting the light assembly out). Take 2 screws and 2 bolts out of each side panel near the lights, fold down the plastic bumper cover retainer and remove 1 bolt behind it. Then remove 1 bolt to the inside of the light assembly and 2 on top. pop out the assembly and unplug. Flip it over and the flat silver box is the ballast. 6 or 8 screws hold it in. Replace. plug in and test without completely reassembling to make sure it works. Takes about 45 minutes the first time, and about 20 minutes each time after.
