I have a 2005 TL and my headlight has stopped turning on unless I switch it on and off 500 times. I've narrowed it down to Ignitor or headlight relay/s. Can someone please direct me to where the headlight relay or relays are?

 

Are both headlights not working or just one? If its only one Most likely it's the igniter happened to me on my 2004 try swapping the ignitors and see if the problem swaps to the other side.

 

Just the pass headlight isnt working. I was thinking there might possibly be a relay for each headlight? I can try to swap the ignitors(I thought I'd tried that but its possible I didn't) but i was hoping to just swap relays as the headlights are so much work to remove on this car.

 

It's possible just have to remove headlight unit completely
