Hid Ballast

[al_typeR]

For those with hid kits fitted (and if any of those have kits from Hids4us) is it normal for the ballasts to hum (like an electrical hum) during use? I have recently got a 6000k kit from them and when i fitted it the other day. Unfortunately One of the bulbs failed on me almost instantly but give them their due they have dealt with this very quickly. However before I refit it i wondered if they all hum or if these doing it are a sign of something more than just the bulb being the problem.

They do hum yes, more so when they are ramping up.

I thought this about my HID Ballast. Im not alone then?

No, its the very high voltages they work at that causes it.
