SOS!!! Help please

[Eldarzhang]

Hi everyone, 

I have a 2010 Lexus rx350 

my headlights keep turning off while I’m driving, and when I switch off from auto they come back on and turn off in 2-3mins again? Any idea why it’s happening. 
FIY, I chanced the bulbs but didn’t help at all

thank you so much in advance, 

best, Eldar Zhang

Do you know if they are HID bulbs? Whenever you change these bulbs, you should wear thin Nitrile gloves to prevent skin oil from rubbing onto the glass bulb. Did you take this precaution?

Check your Headlight relay .

Could it be that the lights are broken?Or bad contact somewhere.
