  Light nuclei might be formed in heavy-ion collisions by the coalescence of
produced (anti-)nucleons or transported nucleons. Due to their low binding
energies, they are more likely to form at later stages of the hadronic
fireball. In this proceedings, we report the transverse momentum and centrality
dependence of elliptic ($v_{2}$) and triangular ($v_{3}$) flow of $d$, $t$, and
$^3$He in Au+Au collisions at $\sqrt{s_{NN}}$ = 14.6 -- 54.4 GeV. The mass
number scaling of $v_{2}(p_{T})$ and $v_{3}(p_{T})$ of light nuclei is
discussed. We also report the comparison of $v_{2}(p_{T})$ and $v_{3}(p_{T})$
of light nuclei with a transport-plus-coalescence model calculation.
