We looked out our living room window tonight, and noticed a red blinking light coming from the automatic light sensor on the dashboard. We can’t find anything that addresses this situation in the owner’s manual. Any ideas on how to make it stop.

In your Owner’s Handbook, look under daylight driving lights.

Are you sure it’s a light sensor and not a security light? My wife’s 2006 Sienna has a red blinking light in the dash to indicate the security system is enabled. Check the Owner’s manual under security/alarm system.

My Lincoln LS has a PATS security light that blinks. It is located in the lens of the light sensor for the automatic headlights. Might yours be the same?

You know, it could be both.
