My question is simple. How hot can the HID ballast can be? I recently installed a customer HID kit for my gs400. But the ballast can be very hot after I turn on the light for more than an hour. This might be the engine heat. But the ballast become as hot as can burn my finger. I just want to know if this is regular or something wrong. Thanks

 

it's engine heat.. nothing to worry about

 

don't put your tongue on it...

..it's fine...unless it's catching fire...
