HID headlights not staying on

[JohnMesa]

Hi guys! I just replaced the HID headlight bulbs in my 2008 Lexus IS 350. However, the lights only stay on for few seconds after I turn them on. I already verified my ballasts and my fuses are good. Any advice as to how to fix this problem?
Thank you kindly!

As a wild guess I'd suspect the LED lamps would run without the HID ballasts in circuit...

I don't think he's changed to LEDs though has he?

Oops, i misread his post....

They are an identical replacement not an upgrade?
