Marker lights

Hello,

If it is night fighting for more than one turn, thinking of turn 5 and later. Once a unit has been lit up by marker lights does it stay lit up or would it have to be lit up each turn?

Do you mean search lights or marker lights?

Marker lights are tau specific while search lights are imperial and CSM generally.

In the case of searchlights, they last for the game turn on the unit targeted and the unit using it

I do mean search lights, Thankyou
