I have had the misterjunk.com kit for almost two years now, and my left bulb is slowly turning yellow and dimming. It has the Hella ballasts, so I figure it isn't the ballast going out, and i know misterjunk uses cheap bulbs. Does anyone know for sure if the bulb is bad or if the ballast is. They charge up fine, but ends up a faded yellow. Any help would be appeciated. Thanks.

Can you put your left bulb into your right bulb. Just switch and see if that is the problem. If the bulb gets dim then there it is. I think it is most likely the bulb.
