Is it common for HID bulbs to make a slight buzzing sound?

[todd0218]

Hey guys i wanted to take a peak at my hid kit before i actually mount the ballast and ignitor. I just plugged them in real fast of course the connectors had to be reversed. Anyway they are working great but i tried them just for a second because i have to send the bulb in they sent h4 i need h1.

The one thing i noticed was the hid bulb was making a slight buzzing sound. I dont know if this is common? Or It takes a few minutes for the hids to warm up, i am just not sure. It is about 10 degrees here in michigan very cold.
I just want to make sure this is not something i should worry about.

thanks in advance,
todd

I have an HID conversion kit for both my lo's and fog's and all 4 ballasts make a slight whistle like noise. I believe this is some type of frequency just like a CRT computer monitor, but the thing that you gotta look out for is the placement of the ballast if you got HID fogs. I had to move mine cause it was interfering with the TPM sensors and cause a chime every ten minutes of so and telling me to check tire pressure.

I have factory HID's and they make a little noise until they get warm.
