Up for sale is my treasured OKAY PASS light. It has virtually no wear or marks except a few tiny marks on the paint from storage. It is the best OKAY PASS light I have ever seen.
As you can see from my header picture, it works. It is currently fitted with a 6-volt bulb, which is correct for the period, but it would just as easily accept a 12-volt one. The wiring came with it and I assume it is the same age as the light. It looks sound, unused and in good condition, but I would advise you to replace it with the appropriate modern wiring if you are going to fit it to a car, because there is the possibility of invisible deterioration to the rubber insulation inside the cloth covering. I think that's about it - the photos speak for the condition.
