Hello, I have 07 ES350 with about 80k miles on it. When driving, I hear a weird buzzing noise from the right-front side of the car. The noise sounds close to how it would sound when I operate the side mirrors. It is short, lasting about 2-3 seconds at most. Its completely random and I notice it only when the car is standing.(waiting for a light to turn green, for example). I have asked my passenger to look for the noise and because it is sudden, short and random, then haven't been able to pin point the location. Its somewhere to the right. It doesn't have any impact other than irritating me for the past few years... Any ideas? Thank you for your time.

Hello, I was considering replacing the regular headlight bulbs on my 07 ES350 with HID bulbs. Can I just purchase a pair of HID bulbs and plug them in place of the existing regular bulbs? My car did not come with HID lamps. Thank you for your time.
