  We analyzed the potential of the LC with $\sqrt{s}=0.5$ TeV, LC$\times$LHC
based ep collider with $\sqrt{s}=3.74$ TeV and LHC with $\sqrt{s}=14$ TeV to
search for excited electrons through transition magnetic type couplings with
gauge bosons. The $e^{\star}\to e\gamma$ signal and corresponding backgrounds
are studied in detail.
