Hi, I was wondering if someone who owns a 09 or equivalent body style XJ could help me out with two measurements.

The height of the front parking sensors from the ground, and the height of the headlamps from the ground?

Thanks so much!

Front floor to above the hub, top of wheel well.
Front = > 28", Rear = < 28" on both of mine.
Close enough to the same measurements, on both cars to suite me.
You don't have much space, above the wheels.

What are you trying to do with these measurements? Are you wanting to calibrate ride height?

Measuring my '09, I get 25 1/2" to center of headlight and 18 5/8" to bottom edge of parking sensor.

Of course YMMV, due to variations of ride height sensors, recent driving conditions, temperature, condition of suspension system etc...

For the record, I measure A=25 1/4", B=18 3/8" bottom edge (after drive, susp pumped up, std wheels) 55oF
