Rear height sensor location(s) on the vehicle on 2004 Lexus RX330

Where is the (headlight) rear-height sensor located?

I don't know exactly but it has to be mounted to the body or frame and have a sensor arm attached to the rear suspension. It should be obvious if you get under the rear of the car with a flashlight and look for it.
