BOAT TRAILER DEPTH INDICATOR MODULE

A boat trailer depth indicator module and method of installation thereof. The boat trailer depth indicator allows a driver towing a boat trailer to position the boat trailer at an appropriate depth in the water on a boat ramp to launch or recover a boat without the need for an assistant. When the boat trailer is located at an appropriate depth in the water, the boat trailer depth indicator provides a signal to the driver. The signal communicates to the driver and/or the helmsman of the boat, for example, that the boat trailer is sufficiently submerged and ready for launch or recovery of the boat. The boat trailer depth indicator module is independent of vehicle or trailer power and can be installed and adjusted quickly without the use of tools.
