The Magen Avraham (Siman 263) permits this L’chatchila (initially), stating that it is not necessary for the husband to light instead. However, the Mishna Berurah writes that it is proper for her husband to light.

Nevertheless, if she has been accustomed to lighting the candles herself until now, she should continue to do so. The consensus among the authorities (Poskim) is merely that it is “good” or preferable for the husband to light in this specific case, but not a strict requirement. Therefore, if she wishes, she may light the candles herself and recite the blessing, especially if this has been her established custom.
