I'm sure you're going to love it !
By the way, in a matter of accuracy, it is the starter that makes the pinging noise, not the ballast. However, if the ballast is not properly mounted or if it has slightly loose windings or plates, it can make sort of a thumping sound when the starter makes its pinging sound.
You'll also notice that different brands of starters have different pinging sounds. Some ping in a higher pitch while others ping in a lower pitch. I prefer the lower pitch.
