My 2005 XJ8L has developed a Cookie Monster like appetite for headlamp and marker lamp bulbs anyone else have this issue? This latest time the marker light melted the socket.

Perhaps it is the vestigial ghost of Joseph Lucas at work giving me a bit of that authentic English car experience. (Of course these days the Germans seem to be making a strong bid for dominance in the electrical issues area).

 

You should chek voltage and amperage to teh bulbs. My guess is cheap aftermarket bulbs that have a higher than normal resistance, causing overheating, just a guess though. I have good luck with Sylvania/Osram bulbs, anything else is questionable.

 

Have been using the OEM bulbs for the markers and the last time I replaced the headlamps (this past spring) had them use Sylvania Silver Stars. This time the headlamp bulbs were replaced with OEM bulbs from the dealer (cannot get my big grubby mits in to replace them myself).

 

I have a 2005 XJR both driver side markers are out the yellow one and the rear red one as well. dealership replaced both bulbs for free. I was told that's normal.

 

I have not had to replace any lamps in either of my Jags. I did replace the headlamps with Silverstars for better vision, but they have been doing fine since their installation.

 

I have gone through two sets of Silverstars in the car, they last less than a year and I got tired of changing them so I don't use them anymore, teh littel whiter light wasn't worth the time fooling with them.

 

WOW! I've had them in my 04 XJ8 since new without any problems! Hi an Lo beams.

 

Just recently bought my 04 XJR. All four sidemarker lights, plus both license plate lights were burned out. I looked at the car during the day, and didn't notice them. I replaced them all and have not had a problem since. I was surprised though that all of these bulbs were burned out.

 

That would concern me too...that's alot of bulbs at one time. If I were in your owner-shoes, I'd check the fuses and make sure the previous owner didn't use the incorrect ones. Maybe the car was struck by lightening?
