Abstract
We summarize the evidence that most Population I Cepheids with periods less than similar to 8 days pulsate in the first overtone mode. Funda mental mode and first overtone pulsators must follow different period- luminosity (P-L) relations. We demonstrate these different relations f or different stellar systems, especially for the calibrating Cepheids in clusters and for Cepheids in the LMC, the SMC, M31, and IC 4182.
