Headlights problems of the 2014 Hyundai Elantra

I have a 2014 Hyundai Elantra, I'm having problem with my left signal. I stopped @ a red light turned my left signal on. I notice my left signal was flashing fast. When it went of it cause my head lights & my lights in the inside to blink off & on. Wen I got home I check my lights and notice the left signal bulb in the front was burned. I went to a auto place and replaced a new bulb. It last for @ least 4 months & it went again acting up. I change da bulb again after 4 months it starts again. I took it to a dealership the bulb was change then. I notice after serval months it starts acting up. I can't keep bringing it to the dealership or to a auto place to replace the bulb. Because it cost me I feel it is a safety hazard. Because everytime I use my left signal my headlights blinks off & on outside & inside of my car. I'm afraid I will be driving & when I'll use that left signal & nothing will come back on. The vehicles in front or back want see me or no what I'm doing. That's a big hazard to my life & others on the road also. My name is (xxxxx), when you will pull it up under the VIN# it's under my mother name (xxxxx) I (xxxx) am the driver of the car. If no answer please leave your name & a number do I can contact u back. I appreciate you taking the time to read my complaint on what's going on with my car. Have a great day & be bless.
