'95 Beta Techno headlight bulb ?s (with photos!)

I took off the headlight cover, and this is what i found:



Anybody have an idea what the replacement bulb is?

Next, this is the male plug. I don't get what the two brass prongs on the top do. Are they for another bulb? (Seems like the only option) If so, what type of bulb?



This is what the back of the headlight cover looks like. You can see the "slot" at the top where the two prongs are inserted:

My guess is the two prongs held some kind of euro running light...but then again I don't know poo

Here's my 96 headlight. Removed when new. Surprised it was not the same as yours. Looks like the same bulb. Bet you could find it at an auto parts store. Many car dome lights use a bulb like this.
