The littlest Higgs model with T-parity predicts the existence of the neutral, weakly interacting, new gauge boson B<sub>H</sub>, which can be seen as an attractive dark matter candidate. We study production of the new gauge boson B<sub>H</sub> via eγ and ep collisions. We find that B<sub>H</sub> can be abundantly produced via the subprocesses e<sup>−</sup>γ → L<sup>−</sup>B<sub>H</sub> and γq → B<sub>H</sub>Q, which might give rise to characteristic signals. Some discussions about the SM backgrounds for this kind of signals are also given.
