We investigate the stability characteristics for dissipative solitons solutions in three-dimensional complex Swift-Hohenberg(CSH) equations. The variational approach is used to gain steady state solutions of complex Swift-Hohenberg equations. Following numerical simulations, the quintic-loss parameter, cubic-gain coefficient, effective diffusion (viscosity) or angular spectral filtering have more significant effect on steady state solutions. In particular, an asymmetric input pulses will always give a stable dissipative spatial soliton for dissipative parameters from this domain. The opportunity to achieve analytically and numerically asymmetrical input pulses propagating toward necessarily stable and robust dissipative light bullets opens possibilities for theoretical, experimental and even diverse practical applications..
