Now you need to mount the light fixtures in the tub. I used the supplied bolts and grabbed a couple of nuts lying the around the garage to mount the fixture. I used a soldering iron to put holes for the screws to go through. You also need to make a slighty larger hole for the wires to come out of the tub. Feel free to plug the screw and wire holes with caulk or the like to stop any possible smell or light leak.
