I have two here, one is a 12V7W M8 (made in France) on the left and a 12V10W 7D on the right.
I'm not sure of the correct one but both will work (I assume the French made one was stock since the lights are Renault), the '90 parts catalog has it as T3097183. They are just under 1.5 inches overall (~1.45 in, 36.5mm).
