Activating the turn signal left or right causes the headlights to suddenly turn off for a second or two at a time. Not bad during the daytime but at night time really creates a dangerous condition. Every-time you go to change lanes and use the indicator the headlights go completely out (Black). I have a service appointment coming up in a week to have someone look at the problem. It's really been an issue with other drivers thinking I'm flashing my lights at them whenever I use my turn signal. Today I looked closer into the problem and It appears as though the turn knob for the headlights that is on the signal arm has become a tiny bit loose. I gave it a good smack right on the tip of the arm towards the wheel and it seems to have fixed the issue (for now) - my lights no longer turn off when I use my indicator. It's definitely an electrical shorting issue with the headlight knob. This has a potential to cause a collision and should be looked at by Hyundai.
