Headlight Switch problems of the 2007 Lexus IS

I've had this car for 4 months and while driving my vehicle my lights will just turn off. This happens while vehicle Is stationary or on the road at low street speed or high highway speeds. Sometimes just the left headlight, sometimes just the right headlight and sometimes both headlights at the same time. Only way to temporarily correct Is to turn the light switch off and then back on for a few more minutes and then the light problem happens again. I've seen numerous complaints. Changing the lightbulbs does not work, I've tried that. I've done research and been on lexis Is forums and people like me have the same or similar problem with the same year and models or similar year and models. I went to dealership to ask about a possible recall for this headlight Issue and they said light bulbs needed to be replaced. I told them I had replaced them already and there answer was replace the whole headlights which run close to $1000. I've heard of people replacing their entire headlights and the same problem persists. Dealership states it's a wear and tear Issue. How Is it a wear and tear Issue when your headlights go out when your driving at high and low speeds at night? and not to mention both bulbs work occasionally but then go out and problem can be fix by turning the light switch off and on again a few times a trip hoping you don't hit anything or anyone. This Is not a wear and tear Issue, this Is a safety Issue and must be corrected before we all have an accident or worse. Please look into this.

Headlight goes out. . . Replace bulb. . . . Goes put again. . . . Will flicker on when I turn the lights on and off but driver side low beam won't stay on. . . Now both low beams will sometimes be out and went put while driving at night. . . . Had to pull over and turn switch on and off several times to get the lights to come on. . . . Kept doing that. . . Will come on without Issues if on high beam.
