Vintage Electroline No. 2 Driving Lamp

Vintage Electroline driving lamp. Was to be used on an old Austin Healey as a driving lamp, matches very closely to the number 75 I have listed. Since they don't match and the British car is gone, I am selling them individually. Worked years ago when I tested them, not sure if it is 6 or 12 volt. Make me a deal on both.
