Yes, our wall mount lights can be installed with a liner. However, you will need a vinyl light sealing kit similar to this. CLICK HERE to view
The sealing kit prevents water from seeping between the liner and the wall when you run the cable through the hole and up to the surface where the light will be connected.
NOTE: This is just one example of a sealing kit. Depending on whether or not you have a niche and/or the hole size that you are running the cable through there may be other options better suited for your set-up. You can check with your local pool supply company as well.
