My 2007 Touring has the auto height adjust feature. I have had Toyota replace it once as a safety item because the circuit got wet and failed with the lights adjusted way down. I have also replaced one bulb at my expense (at 135K miles) and expect the other to go before long. I have always been unhappy with my headlights before, during and after the above. My question is: Are the lights mechanically adjustable? I have tried using the notched adjustment wheels behind the lens to no avail. My lights are still too low and I drive most of the time with high beams and never get flashed. Any advice will be sincerely appreciated.
