I have a factory Bosch replacement fog light assembly.
I noticed the bulb is white in the new unit, however the the bulb in the OLD housing i removing has a blue hue to it?

Are the bulbs interchangeable?

Does it have a blue hue because it burned up?

There are a bunch of brands and types of bulbs for the fog lamps. The light blue color is just how that brand and make is made. I installed Sylvania Silver Star bulbs and they have a blue hue to the bulb. The bulbs are blue but the light is white. The color of the bulb doesn't matter, as long as they are H3 bulbs. Change them in pairs so the light matches.

I will remove the clear light bulb from the housing and reuse the blueish bulb to match the other fog lamp...

turns out the bluish bulb is a PIAA.... So i reused the old guts and the blue bulb in the new housing to match the other side.

My car required two new Fog lamps as one was cracked. (hard to match a new lamp to an old lamp hence the two new units.)

I kept the good fog lamp as it only has 55k miles on it if somebody is looking.
I put the new guts into it and the fresh clear bulb.
Would make a great way to replace a cracked lamp and match your current lamp without having to replace both lamps like i did...
