What’s the weight for and how do I install it?

The HID underwater fishing light unit is designed to float, this maximizes the amount of light projected, and keeps it off the bottom. The weight can be attached to the marine grade cord with our supplied zip ties to hold the lamp in place below the surface. The weight can be adjusted on the cord by sliding it up or down. As a good rule of thumb, we recommend that you keep your HID fishing light at least 3′ to 4′ below the lowest tide to keep it away from boat traffic.
