When the car was new in the US in 68, were the bulbs in the parking and front side marker lamps on a non-RS 68 white or yellow?

The parking light bulbs (clear lens in the lamp modules) were Yellow/orange.
The side marker bulbs are clear

Don't think there's any difference in color between RS or standard but my RS had clear bulbs that had an amber paint coat over them. I still have them, but replaced them because of their age, the paint had begun peeling off.
