Hello. I have a 2006 Jaguar XJ8 and today I noticed that the passenger side low beam is dimmer than the driver's side and that it flickers. The flickering is not huge, like flashing, but more subtle. Even so, it's a bit noticeable. So, my first question is - is it the bulb or could it be something else, like an electrical flow issue?

Secondly, I hadn't thought about it until now, but apparently these cars can have two types of headlamps - HID and standard bulbs, I suppose? Is this correct? How do you tell what type of bulb my car has? If I need to replace it, I will definitely need to know what type of bulb. Sorry for my ignorance on this issue. Any help would be appreciated.

Thanks.

 

HID has a round projector and is white or blue, regular is reflector and yellow.


there’s three grounds that go bad over time. otherwise your bulb or ballast may be going out

 

Thanks for the info. I truly appreciate it. This is a shot of my headlight:



Is that HID?

I'll check the ground. However, mine is not flickering that badly at all. It's barely noticeable. Also, the passenger side is also dimmer than the driver's side light.

 

yes it’s HID

 

Awesome. Thank you so much!

 

I had a flickering HID lamp on one side. The lamp unit was faulty, there was a broken contact. I changed both bulbs and no flickering. I had already replaced the behind the headlight grounds before this as a preventative measure. I initially thought it was the ballast that was faulty after reading up on the problem, which is quite pricey, but thought I'd try the bulbs first and got lucky.
