A simple method for calculating the asymptotic $D$ state observables for light nuclei is suggested. The method exploits the dominant clusters of the light nuclei. The method is applied to calculate the $^4He$ asymptotic $D$ to $S$ normalization ratio $\rho^\alpha$ and the closely related $D$ state parameter $D_2^\alpha$. The study predicts a correlation between $D_2^\alpha$ and $B_\alpha$, and between $\rho^\alpha$ and $B_\alpha$, where $B_\alpha$ is the binding energy of $^4He$. The present study yields $\rho^\alpha \simeq -0.14$ and $D_2^\alpha \simeq -0.12$ fm$^2$ consistent with the correct experimental $\eta^D$ and the binding energies of the deuteron, triton, and the $\alpha$ particle, where $\eta^d$ is the deuteron $D$ state to $S$ state normalization ratio.
