The recommendation of Jaguar is to install only 55 W capacity lamps. Cap shape is also important - H7 type may only be used with base PX26d. When you need replacing head light bulbs in Jaguar S-Type 4.0, make sure you install effective and strong agents. Anyway, cars with 4.2 engine made by Jaguar will occasionally need bulb exchange. Work of headlamp in every Jaguar S-Type is quite effective and appropriate. For the cars with AJ-V6 engine number produced in 2007 bright and long lasting lamps were used. Lots of S-Type owners admit that 12 V lamps tend to be less and less effective.
But power of 55 W is just optimal feature, real light of 12 V lamp may be much stronger. Relieve the holder at back of S-Type head light module, all 4.0 engine cars are serviced like that. Usually you won’t place the PX26d lamp type into holder in 2002 S-Type without help. The obvious thing is that other cap than H7 won’t suit Jaguar’s headlight module in 2005 model year.
Don’t also try to put into 1999 Jaguar headlight wrong type – choose H7 variant and PX26d kind of base. Take into account all recommendations for 2000 Jaguar S-Type and drive safe enough. By taking the bulb holder in S-Type cars with 2.7 motor be careful not to destroy it. Capacity of the lamp on the pack should be 55 W and volt feature - 12 V.
