So i turn on my headlights and everything is normal then after like 30 seconds the passenger side head light bulb slowly changes to a halogen like color. I have the OEM bulbs on here. My other one is perfect. Im talking about low beams btw. Anyway is this a problem with my bulb, ballast, or something else.

<----Look at my sig see how it kinda looks like a halogen.

 

swap the low beams left to right to see if it follows the bulb
Otherwise its just time for new bulbs
