Are you measuring them using the same ground connection point with your meter?

Running/parking lamps or stop/turn lamps?

LED or incandescent bulbs?

Original or aftermarket lamp assemblies?

You didn't answer this question.

Do check the grounds as suggested by steve(ill), especially if you did not use a good, common, and clean ground for making your reported voltage measurements.
