1)I'm thinking of purchasing new HID or LED lights for my car but I don't which kind I should go with. I've spoke to a couple of vendors and each have their own opinions on which one they would recommend.. I'm not looking spend no more than $150 for HID/LED lights. Any recommendations will be much appreciated.

2)My car makes unpleasant creaking noises when I turn the steering wheel in a neutral position or when I'm turning in low speeds (5-10 mph). I've read a couple articles on forum on this website and Type_Audi (https://www.audiworld.com/forums/a4-...pdate-2784337/), seems to have the same problem. I've been considering of purchasing a new control arm, but I have no clue on which one I should buy and how much I should be spending. Again, any help or tips are appreciated.

I have a couple more questions..but this is enough for now.
Thank you in advance for any recommendations or tips you may have.
