Replacement Fog Light Bulbs

I just purchased this fog light kit from McDonough Toyota. 00016-35220 Toyota Tacoma Fog Light Kit 2012 - 2014. I really need fog lights on my 2013 Tacoma because I drive a mountain road to work every day. Sometimes the fog is so heavy, the visibility is no more than twenty feet. When it's raining it only adds to the problem because of all the rocks on the road. I asked the sales guy at McDonough if the lamps where white or amber and he couldn't give me an answer. Does anyone here know? If they're white bulbs, can I replace them with aftermarket amber ones?

 

Pretty sure the bulbs are white. This article is worth a read:

If you really want yellow light his method of coloring the lenses looks like a good way to go.
