I was thinking maybe my HIDs. Oh and the noises were going on before the LEDs were put in but not sure after or before the HIDs. Also I thought LEDs use less power then regular bulbs. The noises don't bother me to much considering I never hear the A/C or headlight whine because my music drowns it out and I never use the dimmer. But still want to track down the issue.

thats pretty weird with the ac and the dimmer. i have had the engine rev noise before when i had an amp hooked up. i had put the power and signal wires right next to each other and it would make that same noise. a friend of mine thats good with stereos told me to run them on separate sides and the noise went away. has this been going on for a while or just recently started
