The Guide (division of GM) featured the light from about 1940-42.It was sold under the "Guide Super Ray" combination driving and fog light description in the Guide catalog.The lamp was sold as a "passing lamp" by the GM car divisions.
Guide described it as "The light beam projected by this lamp fans back from the long range spot in such a manner that the imeadiate foreground as well as distant points are plainly illuminated from ditch to ditch, with no glare to the uncoming car".
The description in the 1941 Chevrolet accessory catalog calls it a passing lamp (refering to its use when meeting an oncomming car)....And says"The approaching driver can see the road better when this light is in use, and its long range beam provides clear visability beyond the limit of conventional lights"...In 1941 it cost $9.995 where as a PAIR of the conventional 1941 fog lights cost $11.00.The lamp was rather large in size and was usually mounted as one single light only
The was another large and expensive light back then and common to be found on laeger cars.It was the Trippe Passing light.This was usually installed on Packards and Cadilacs (1941 and up Cadillacs had optional "built-in" fog lamps).
The passing lamps were mounted to the fron bumper brackets as fog lights were.For a 1937 and up Chevrolet a pair of the proper year fog lights look much better and fit in with the proportions of the car better...also can be a good aid in night time driving.
I saw a passing light at a swap meet yesterday.Looked almost new and had a Firestone name tag/emblem on it so they were sold under many names...The vendor was asking $395.00 for it.The lens/rim and emblems were changed slightly ,depending as to what name was on them and who sold them.
My story for today
