Above photos of the 1929 Auburn Cabin Speedster and 1929 Stutz M-8 from http://www.tuningforum.cz/
the above 2 are Du Pont cars, the bottom I don't know.. probably another model of Du Pont, but it has different louvers on the hood sides
As far as I've seen, only Ruxton and Du Pont had the Woodlight as standard lights. I read somewhere they were lousy for lighting the road ahead.
