According to Jim Carter, the 55-56 Suburban tailgate light could be fitted with a factory backup light per this pic. The switch was mounted to the shift linkage on the column. Can't find that option for 57-59. That original light and it's original switch can be found on the same isle as the chicken lips and hens teeth.
