Lots of S60 owners admit that 12 V lamps tend to be less and less effective. Anyway, cars with 2.3 engine made by Volvo will occasionally need bulb exchange. Use up-to-date optical devices in Volvo S60 2.0 headlight system. Efficient and bright head light in Volvo S60 is the reason of safe night drive. The recommendation of Volvo is to install only 55 W capacity lamps. For the cars with B5254T2 engine number produced in 2005 bright and long lasting lamps were used. The recommended type is H7 and cap also should have the base PX26d.
It’s obvious that only H7 type of lamp will be suitable for Volvo in 2005 year of production. To install new lamp in S60 with motor 2.5 relieve bulb holder at the backside of headlight. Usually you won’t place the PX26d lamp type into holder in 2010 S60 without help. Note that you may choose real power more than 55 W, providing the voltage stays at 12 V.
By taking the bulb holder in S60 cars with 2.0 motor be careful not to destroy it. It’s easily bad idea for 2005 Volvo owners to buy other than H7 type bulbs with base different from PX26d. Take into account all recommendations for 2003 Volvo S60 and drive safe enough. Remember that any lamp is 12 V of voltage, power level on the pack is 55 W only.
