With these LED or sealed beam headlights?
Do you have access to a FSM for the wiring diagrams?

Did you check (4) 10a fuses 3-4-5-16?

 

Yes, I've checked those fuses and more. I dont have any diagrams unfortunately. Currently have Inspired Engineering LED headlights. Not sure if the fact they are LED, it may have shorted something? Strange that the headlight delay module was buzzing.

 

Follow the link I posted and you can buy a FSM.

 

RESULTS: Headlight delay module shorted out, hence why I heard it audibly buzzing. That short resulted in a hairline break in the 30 amp fuse in the PDC.

Regardless of the short, I've seen some LED headlights do not seem to cooperate with XJ's factory wire harness and headlight delay module. Plugged in, the headlight delay module may result in some brands of LED's always remaining on (slightly and dimly) during vehicle operation; even when NOT equipped with DRL's. I have pictures of this strange occurrence and have seen it in similar headlights install in other XJs (see below). Weird.

Honestly I really do not care for the headlights I have (Inspired Engineering). They have virtually no cut off which requires me to aim the headlights way down in efforts not to blind on coming drivers. When the high beams are on, the light is projected in the tree tops. Just my opinion, but not for me.

Not related to the problem directly, but I just ordered a set of Truck Lites after hearing so many good things about them. I am eager to see the upgrade and difference.

Thank you to those who offered suggestions and experience!

 

 

Man... I would never have figured that issue out. Thank you for filling us in!

 

You are going to love the Trucklites! I have had mine for over a year and I am still very impressed by them. Its nice being able to see at night. The brights are bright enough that I feel no need for a light bar either.

 

Where have these been all my life!? Huge fan of Trucklites.

 

but how will the truck lights do in snow ??

do they have a heater grid ?

 

Maybe alright, maybe not. They're not heated. Last season I ran LED headlights through our Maine winter and I didn't have any issue (in a variety of temperatures and snow conditions). That's what the halogen PIAA driving lights are for

 

JW Speaker does offer a heated 5x7 model now
