We introduce the notions of $TL$-ternary subsemigroup and $TL$-bi-ideals of a ternary semigroup. We redefine $TL$-ternary subsemigroup and $TL$-bi-ideals using $T$-product on $L$-sets .We introduce the notion of $T$-intersection of $L$-sets. We establish that $T$-intersection of two $TL$-bi-ideals is again a $TL$-bi-ideal. We establish necessary and sufficient conditions for a pre-image of $L$-set under homomorphism to be a $TL$-ideal. We introduce the notion of $TL$-level sets. We characterize $TL$-bi-ideal by $TL$-level sets.
