Dave:

Are you talking about the lense shown in the photo below? They were a mil-spec lense (2540-00-930-2044) intended to convert the blackout markers into turn signals. However, most of the pre-67 Jeeps that I saw simply had the blackouts with the guts removed in their original lenses. The NSN for the lense did not come into being until April of 1966.

At the back end of the M38, the existing factory left rear lamp was used for signals as it already contained a dual filament Stop/Brake lamp

The reason that lamp could be used was because it had two light bulbs for service drive...one was the marker (bulb 623 or possibly a 1251) and the other was for brake (1683 if I recall correctly). While the bulbs did in fact usually have dual filiments, that was to enable them to work on 24 volt. They only had one contact at the base of the bulbs.

The large round commercial light added to the rear right was only a single bulb, so there was no right rear marker light. The addition of a left taillight to the right side meant you did not have a blackout brake light on that side. The small blackout brake lamp was standard on the Cdn2 and Cdn3, but in service most mechanics did not worry about the lack of a right marker light. We were exempt from the provincial highway traffic acts so unless the CFTO called for it, we wouldn't bother.

Signal arms were usually either do-ray 999 or signal stat 800. For those who are missing their little green lense for the signal stat, there is a seller on ebay who has been selling them for years: http://www.ebay.com/itm/OLD-Vintage-...2OaTCQ&vxp=mtr
