i dont know what the "buzz" is about
il share my hid experience i went in to a local hid shop
installed fog lights with just a digital ballast
none of that cheap plastic.fog lights work just fine
converted h11b to h11 they tried the same type of ballast as fog lights flickered off
then they brought in a big canbus digital ballast and works fine...
never heard a buzz even without the canbus and all that cost 250 including tip
btw they are not connected to my battery and no splicing
