New-old-stock Soviet pilot lights that operate on 9V. These lights have a unique bakelite frame and metal bezel. The lights come with a 9V bulb but can be used with any voltage bulb that fits this type of socket. The diameter of the light is 12mm and the diameter of the mounting hole is 8.1mm. Includes a wavy washer and knurled nut.

Note: There can be small differences in the appearance and tint of the lens and color of the bakelite. A small 0.1” notch must either be filed into the 0.625” mounting hole or filed off of the fuse to flush mount with a panel. The small bulbs can come loose during shipping and reseating the bulb is recommended before use.
