Worth 4 Dot Test from Good-Lite (Formerly Richmond Products, Inc.)

The Worth 4 Dot Attachment fits on your WelchAllyn, Heine or Keeler transilluminator and supports Worth 4 Dot testing using any of our red/green glasses. Compared to conventional Flashlight versions the Worth 4 Dot Attachment lets you avoid cumbersome flashlight units and avoids D Cell batteries, which can become weak or even leak and are not rechargeable.

Rather, the Worth 4 Dot Attachment uses the transilluminator or muscle light attachment which everyone has and keeps recharged.
