No mention of a direction option and I doubt there was a "standard". Either half the applications are 180 degrees off or, maybe the bulb rotates? Probably too long (1.25") to be used in the marker lights and even the 1-1/2" square "bulbs" are probably too big for marker lights. Although they'd probably work dandy for the ceiling lights if secured with a dap of RTV silicon sealant.
