Sprint high beam indicator

I need a high beam indicator ligh assembly for my 1963 Giulia sprint. It mounts on the lower dash under the ignition key and next to the choke indicator light. I believe it would be blue in color and have a 7 mm hold to screw the outer lens on. I don't have one in the car. It came to me with a red lens glued to the dash and nothing behind it. Thanks Bill P
