Angular distributions for the elastic scattering of ${}^8\mathrm{B}$, ${}^7\mathrm{Be}$, and ${}^6\mathrm{Li}$ on a ${}^{12}\mathrm{C}$ target have been measured at $E_{\mathrm{lab}}=25.8$, 18.8, and 12.3 MeV, respectively. The analyses of these angular distributions have been performed in terms of the optical model using Woods-Saxon and double-folding type potentials. The effect of breakup in the elastic scattering of ${}^8\mathrm{B}+{}^{12}\mathrm{C}$ is investigated by performing coupled-channels calculations with the continuum discretized coupled-channel method and cluster-model folding potentials. Total reaction cross sections were deduced from the elastic-scattering analysis and compared with published data on elastic scattering of other weakly and tightly bound projectiles on ${}^{12}\mathrm{C}$, as a function of energy. With the exception of ${}^4\mathrm{He}$ and ${}^{16}\mathrm{O}$, the data can be described using a universal function for the reduced cross sections.
