I am working on adding the Gopro Hero 2 and a Kayak light to the Jackson Cuda kayak. I wanted something where I could use one mount and switch between the two without dropping a load of money. Simple, use a section of 1/2" PVC pipe 4 ft long. Attach an end cap on the bottom and a threaded connector on top. Here are the pictures of the home built light using a flashlight.
Materials List:
1. PVC adapter with 1/2" male (threaded) on one side and 3/4" female (slip on) on the other;
2. Nightlight plastic globe cover
3. Electrical tape
4. Small LED flashlight small enough to fit in the 3/4" adapter (I picked mine up free at Harbor fright with a coupon avalible almost all the time online.)
Step 1- Place the flashlight into the adapter and wrap with electrical tape;
Step 2- File the opening of the night light globe to fit the flashlight and
Step 3- Put the flashlight into the globe slightly 1/4" should work and electrical tape it in place.
This is simple and effective. Just use something pointy like a rod tip, pliers, etc and turn the light own then screw it into your mount on the pole. You are now legal to kayak fish at night in NC.
