I couldn't find a thread for this particular issue anywhere so I thought I'd make an account ask.
I've recently bought a used 2005 Lexus IS250 Sports Luxury. It has an automatic setting for the headlights - but it has a weird quirk.
Every single time that the low-beam lights come on or off automatically, the car makes a very loud "beep" sound. And I mean it when I say loud... it's so loud that it startles me every time and actually hurts my ears a little.
The car makes the sound even if I adjust the headlights manually! No matter what happens, if the low-beam lights come on or turn off in any situation the car beeps once really loudly.
I've scoured the internet and have found nothing related to a problem like this.
Does anyone know what could be going on? Is it normal?
EDIT: I've checked all the lights and they are working perfectly, including the AFS system. Also the beep occurs whether or not the AFS system is enabled or not.
