The recently discovered $\eta_1(1855)$ and the previously observed$\pi_1(1600)$ state present a valuable opportunity for the investigation of the$J^{P(C)}=1^{-(+)}$ light hybrid nonet. In this study, we employ asemirelativistic quark potential model to examine the masses of the$J^{P(C)}=1^{-(+)}$ light hybrid states. The static potential, which portraysthe confinement force between the quark-antiquark pair in a hybrid system, isborrowed from the SU$(3)$ lattice gauge theory. Additionally, we utilize aconstituent gluon model to analyze the strong decay characteristics of theselight $1^{-+}$ hybrids. Our findings suggest that the $\pi_1(1600)$ and$\eta_1(1855)$ states could be potential candidates for $1^{-+}$$(u\bar{u}-d\bar{d})g/\sqrt{2}$ and $s\bar{s}g$ hybrids, respectively. Toensure comprehensiveness, we also investigate the isospin partners of the$\pi_1(1600)$ and $\eta_1(1855)$ states within the $1^{-(+)}$nonet$-$specifically, the $(u\bar{u}+d\bar{d})g/\sqrt{2}$ and $s\bar{q}g$($q=u$ and $d$ quarks) states. We propose some potential decay channels whichcould be explored in experimental settings to detect these undiscovered states.
