Just installed those McCulloch balasts with Philips bulbs and as soon as I turned on my headlamps one of the bulbs flashed and did not come on again. I took it out and it seems that there is moisture inside the bulb (the moist part of the bulb is arrow #1). Right now it is under my table lamp getting dried off. There was a lot of condensation tonight so that might be the reason why this happened. Anyone expirenced anything similar? I am exchanging my bulbs in any case.

Also #2 and #3 are not connected. Are they supposed to be?

 

didn't i warn you about those mcculluch ballast?? lol j/k man. anyways that build up is pretty normal. on my BMW OEM bulbs i have a bunch of yellow build up. i have a burnt out HID bulb right here with me. and the only differncce it is to a working bulb is that there is some build up/crap on the outside of the small ball like thing in the middle. but still inside the bulb itself

 

umm.... the moisture you talking about, that's not right. if there is moisture inside the bulb it can easily burn out the bulb, that's what all about the water proof of the housing.

also, your bulb has a blue tint on the bulb?!?!?! if there is, it's not philips?

 

blue tint looks like an object behind the bulb or a reflection. my blue bulb from mccuulluch looks totally different. its like totally blue.

 

ah gotcha, just wanted to make sure
