Hello, First of all I am new here. Just picked up an 05 TL, Love it so far. Well my question is concerning the turn signals on the headlamp. All my blinkers are working fine, But I did notice that my turn signals on my head lamp wont stay on (Parking lights) when I turn the lights on. Anyone familiar with this. Im guessing it could be the bulbs? But it is both sides so I find that kind of weird.. Also my when I use my remote to lock or unlock the doors the drivers side will not lock or unlock. I have to manually unlock it with the key, but all the other doors work. Not even pressing the lock or unlock button on the door panel works. But if I manually pull or push the drivers side lock it will lock and unlock all doors. Any advice would be helpful. Thanks!

 

im pretty sure those are dual element bulbs. Kinda like two bulbs in one. It is possible that both have failed.
