Hi I started to have a problem recently with my 09 LS460 AWD. When I start the car if I turn on my high beam the will turn on for a few seconds and then turn off and will never come back on. Even if I turn off my low beam to get the DRL on they will not light up. I have to turn off the car and restart it to be able to turn them on again for a few seconds before they shut off automatically. At first I thought that was the LED bulb that were dying (they worked perfectly fine before) so I changed them for brand new ones but the new ones are doing the same thing. I changed nothing on the car recently the battery is about a month and a half old. Could it be a relay or something like that?

Thank you for your help anything will help I know nothing about this car i bought it 2 months ago.
