(2005 Jaguar S-type 4.2L-non sc)

Had failed brake lamp indicator, so I stopped in to pep boy an got correct replacement for car according to sylvania book (bulb#7225). Replaced bulb yesterday and drove today, no problem, warning indicator off. This afternoon I thought that it maybe time for remainder of bulbs to be replaced so I stopped in advance auto and got remainder of bulbs for rear light housing (except reverse bulb). Just finished reinstalling everything. All bulbs are working!!

Forgot to do one important thing!!...check the bulb wattage

All of the sylvania bulbs are rated at 13.5V 21W...the bulbs that just came out of the car are rated at 12V 21W......that's 1.5 more volts per bulb

Before it gets dark do I need to go back outside an take these bulbs out and put the originals back in an visit the high price jag retailer before I fry something!!!

 

No, all is well. Cars actually operate at around 13.5 volts although the system is called 12 volts.

 

Thanks Mikey for the quick input. I know jaguar is specific about a lot of stuff, especially the electronics and I don't want to blow any electronic module while doing a little preventive maintenance to save cash.
Next, I got to tackle the front bushing issue (front lower control arm).
