The best decision is to purchase for Volvo XC60 2.4 efficient up-to-date bulbs of reliable producers. Actually, cars with 2.0 motors produced by Volvo sometimes need bulb change in headlights. You should keep up with Volvo’s recommendation to put into vehicle headlights only 35 W capacity bulbs. Safe drive at night on Volvo XC60 is possible with working head light only. When time passes, 12 V voltage lamps may be less effective in XC60. Producer used in 2013 year of production quite effective bulbs for vehicles with D5244T17 motor number. With this base type must be PK32d-2 and cap of lamp is D1S.
The needed cap type should be only D1S, otherwise Volvo made in 2010 won’t take the bulb. Usually you won’t place the PK32d-2 lamp type into holder in 2013 XC60 without help. But power of 35 W is just optimal feature, real light of 12 V lamp may be much stronger. Relieve the holder at back of XC60 head light module, all 2.4 engine cars are serviced like that.
Note that having bought other bulb than PK32d-2 and cap type D1S you won’t fit it into 2013 Volvo. By taking the bulb holder in XC60 cars with 3.0 motor be careful not to destroy it. Remember that any lamp is 12 V of voltage, power level on the pack is 35 W only. If you keep up with all the rules, 2012 Volvo XC60 headlights will serve you much more.
