The trim level of your vehicle can denote which options it has. You might notice these badges on the trunk lid of cars you’re behind in traffic; Camry LE, Explorer Eddie Bauer, Camaro SS, etc. Sometimes that trim level will determine which part your vehicle has, since a higher-trim model might have a larger engine or more advanced electronics.
