It looks like Harley have used the same picture as the parking light accessory, but made the lens red. The 1935 catalog shows the parking lights at $3.25 a pair with red lenses, and by 1941 the rear facing ones are $3 a pair with red lenses, and all chrome too.

Is there a difference in the angle of mounting?The ones shown look angled to match the fork perches.
