Head/ Fog Lights
 

OK, So I took out the metal fog light flute inside the headlight assembly. I assembled everything back without it. Now it acts like a regular or extra light. I guess the flute's purpose was to reflect the light down? Anyone?
But my real question is, what fog light replacement bulb is closest to the Silvanya Silverstar? And No I don't want other colors like blue, green, red, pink...etc.
