The bulb is a 2 contact bulb ( bottom looks like a 1157 ) that is a single filament. The 2 lower contacts are the hot and the ground . It doesn't ground through the side pins like most of this style bulbs . I will go out to the shop and see if I can find the package . I needed one for my K20 and they came in packs of 2.

I found it !!! 1004 is the number .

Hope this helps !!
