The metal-poor, fundamental-mode (P0) and first-overtone (P1) Cepheids in the dwarf galaxies IC1613, WLM, Pegasus, Sextans A, Sextans B, and Leo A are compared with the about equally metal-poor Cepheids of the Small Magellanic Cloud (SMC). The period-color (P-C) and period-luminosity (P-L) relations of the seven galaxies are indistinguishable, but differ distinctly from those in the Large Magellanic Cloud (LMC) and the solar neighborhood. Adopting (m-M)⁰_SMC=18.93 from independent evidence, one can determine reliable distance moduli for the other dwarf galaxies of (m-M)⁰=24.34±0.03, 24.95±0.03, 24.87±0.06, 25.60±0.03 (mean for Sextans A & B), and 24.59±0.03, respectively.
