I am not sure how long this Leica M frame line illuminator has been available, but I just spotted it being listed for sale on eBay for $150. Here is the product description:
Don Goldberg, DAG Camera Repair, has engineered and built a much needed accessory for shooting in dim lighting conditions. A Frame Line Illumination for your Leica M2, M3, M4, M6, M7, M8, M9 and Monochrome series of Leica Rangefinder Film Cameras. It also comes in handy if you have weak frame lines. How it works is simple, place it in your accessory shoe, flip down the light illuminating head and press the button and the light will illuminate your frame lines for approx 2 minutes. You can adjust the length of time the illumination is active with a simple screw adjustment, for as little as 30 seconds to hours. This will help you frame the proper composition when shooting in dim lighting conditions. Most of the Digital series of Leica M cameras has this feature built in. DAG is offering a full 1 year warranty and it operates with a simple battery. Once you have tried it, you will not shoot film at night without this practical accessory. It makes a World of Difference! I am offering Free Shipping within the United States.
