Lights stay on permanently

[Mark Hooper]

Hey guys, this is on a 2005 GS300. Just last night a friend came up to me and told me my lights were still on. As you all know, I’m auto mode they should automatically turn off after 30 seconds or so. But now they never turn off. This has happened twice so far. I can manage the situation by manually turning the lights on and off but I shouldn’t have to. Any idea what could be the problem?

Sounds like the ambient light sensor (possibly located in the windshield area) is fault or even just obscured with dirt which can give a false reading of the available light?
