In a nutshell, my headlights, in auto or in the "on" position, sometimes flash on their own rather quickly. It is rare when it occures. When they go on and off, messing up, they flash on and off about 1 second off then back on, a second off then back on. It stops when I turn em off then back on. Like I said, it doesnt happen often. I rule out the sensor for the auto mode since it also happens when I manually turn them on. Any help would be appreciated. Oh, one more thing, it is not just one light but both headlamps.

 

Sounds like you may need a new set of HID elements, These fail like that after a certain # of hours. Mine were doing this and I replaced the pair for $80, -10% code from Super Bright LED Car Lights, LED Bulbs, HID Headlights and Accessories (HID-D1S-D1R-D1C)
Now if it is the control module under the lights they are a bit more

 

Agree with dsetter.

Super bulbs good choice.

Search bulbs on the forum and you will get plenty of hints on how to access and change the bulbs. Small hands, no need to remove bumper cover, etc.

New bulbs fixed mine.

 

Thanks for that advise, but my jag has halogen bulbs.

 

I haven't gone through that on my Jag, but I have on other cars.... check for proper electric ground??

 

The XJs all have halogen high beams-do you have HID low beams or halogen low beams? If they are halogens, replacements are cheap and easy to find at any parts store, might as well try a couple of new bulbs.

 

Except the ones with Bi-Xenons fitted

 

All my bulbs, low, high, and fog lights are halogen. I can try new bulbs, but, both blink on and off together. I am an electronics technician, radar tech, but still electronics. Typically, 9 times out of 10, 2 modules wont misbehave together unless something inline, ahead, of the two modules has malfunctioned. I do like the possible improper ground possibility. Nevertheless, anything is possible.

 

I'm also getting intermittent flashing during daylight and on 'Auto lights'. I see the sat-nav keeping switching Day to Night and back, plus lights-on indicator comes on. Not investigated so far, I just turn lights to Off, but will no doubt get round to looking at it some time.

 

Have a look at this thread

I know the symptoms are slightly different but a bit of cable waggling might be in order.

 

We recently had to replace the turn signal stalk on my wife's 05 VDP. Whenever she would signal right or left, it would cause the bright lights to flash on, and sometimes stay on. This is the stalk on the left side of the steering wheel. As you know you can push this stalk forward and turn the brights on or pull it back and flash them on until you release the stalk.

 

Very helpful thread, possibly. I will definitly look into what that person did. I have like symptoms, near identical, like the auto column not working.

 

I had the same issue as RSCULTHO above. Replaced the turn signal stalk and all is well. I don't know if the lights were actually flashing or not, but the nav screen would flash from day to night. When driving at night the nav screen did not flash, but the dash lights would flash bright for a brief moment.

 

I have the same problem with the high beams. I just bump it a bit forward and all is good. I will be looking for a used one sooner or later though. I don't know for certain but a bit stronger spring might resolve the problem. How to do that??? I recon you would need to tear into it because I see no repairs just replacement.

 

Hello guys,

Luv my 2005 XJ8L Jaguar. Good to see this Jaguar forum for us Jag lovers! Well, I have a problem with my light flashing on/off while in auto mode. When I turn vehicle off they strobe light flash as well. Had the sensor fixed but problem is still there, any suggestions?

Marshall,

My 2005 XJ8L has the same problem with the headlights flickering on/off in auto mode. No rhyme or reason to the frequency of the problem. Will go weeks without it happening, and then it will occur multiple times in one night. When I manually turn the headlights on/off it cures the problem. For now I am just going to switch to manual until I read about a cure.

 

It's happening to me too, and intermittently. so difficult to pin down. Local indie says he'll take a look at next service, in the meantime it's "Doors to manual" as they say.

 

Well, since my previous post... had the HID lights replace as well as the sensor in the dash & yet still get the flickering/flashing of both lights randomly when they want to or when I park & lock the door at times. Not sure how to solve this... Luv my JAG, hanging in there. I guess, I'll keep looking to see if anyone has fixed these types of issues.

Not sure if my symtoms are connected or not. My headlights also will turn off for a second or two while driving. This is while in Auto or Manual. I will turn the headlight switch off and on and they will come back on. Kind of scary when on coming traffic is thinking your are flashing them or dangerous if a cop sees that and wants to investigate why i am flashing him/her....I also get a message on my info screen saying "Lights are off" even when they are in manual off in the daytime. It seems to think it is dark outside and is telling me to turn on head lamps. Any ideas what is a fix?

 

forgot to include that i have an 04 VDP
