2006 HID Auto Leveling Sensor Picture

I agree that the part needs to be replaced. The applicable warranty would be for 3 years / 36K miles. If you don't want to replace the part I suppose you could put black tape over the dashboard warning lights, but that seems to be a half-a__ repair.

The part # is 89408-47010 and is pretty expensive at $347 MSRP, $264 plus shipping here:

mine went within a year on my 04. they covered it. of all the things i would never ask for on a car, that has to be near the top.

 

Thread with some more info here , including the fact that parts can be bought from a lexus that fits, if that happens to be cheaper.

How to aim headlights on a prius, just saw this article today. This also contains advice on lubing the sensor to keep out moisture, I should probably do this soon.

As to your last question, I suppose a resistor could be place in the connector to replace the sensor, but are you sure your car's height will always stay the same, they really are bright. I really do like my HID headlights, no problems so far, I'd recommend just buying salvage, and adding some silicone grease as recommended above. I drive in the country a lot, last year I zip tied on one end a loose piece of inner tube rubber as an additional cover on the sensor to help keep out moisture and dirt. I fastened this on the body of the sensor, draped over the little arm, I believe your picture has it upside down as to the cars connection.
