Chevrolet never made or offered a right side lamp or bracket for any truck of this period. The first I know of is for the AD trucks '47 and later. Until I ran across this thread, I did not know that Jim Carter was offering a RH lamp with no hole for illumination of the license plate. I checked my catalog, and sure enough, there it was. My guess is that, after a number of inquiries, Jim decided to offer a "fantasy" Accessory RH lamp to go with his "fantasy" RH bracket. The bracket is a dopey looking item with a meaningless continuation of the vertical strap sticking up, for no reason other that to display the CHEVLITE stamping. My guess is that the RH lamp was quickly created by eliminating the hole, with no thought given to the fact that you could no longer install the appropriate bulb.
I make some parts for Jim, including the flexible conduit that protects the tail/stop lamp wires and the clip that holds the conduit at the lamp end. I also make the cab mounting kits for '31/'36(hr) and '36(lr)/'38, as well as the horn wire conduit.
As for the reliability of the original design of the subject lamp, I have had the Car version on my 1935 Chevy for 45 years and had a pair of originals on my '36 1-1/2 ton truck for a few years before converting them to LED. I had no issues of reliability on either of them. Admittedly, the design LOOKS totally sketchy, it just turns out that it works. My 6 volt LED kit came from The Filling Station. I installed them in lamp buckets that were damaged beyond restoration to original operation. They are FANTASTIC!!
I will call Jim tomorrow to learn the origin and thinking behind his ill conceived RH lamp.
I am fortunate to have a substantial stash of original lamps and have had no need for one of Jims reproductions. I just inverted a LH lamp and installed it on the RH side and ignored the open hole, now facing down. I made my RH bracket from damaged remnants of a LH bracket.
Philippe, Wasn't there an original lamp on the fire truck when you got it from me? Might have been too rough to use.
