Solar Shield sunglasses or any brand in the wrap-around style. I found mine for $19.

one that can be powered by a 9V battery. eBay
has the best selection; the camera I bought was

wire no larger than the diameter of the temple of

connectors. Cut back the insulation and strip the
wires on both halves of the cable (Figure D).
Now prepare your extension cable. Cut a 4' length
of 4-conductor wire, then trim the insulation back
and strip the wires on both ends (Figure E). Cut 2
pieces of heat-shrink tubing and slip them onto
the extension cable (Figure F). Twist all the connections together, taking note of the color-coding.
Then attach your 9V battery to the red (power)
connector, and check to make sure you’re getting
video and audio by hooking the cable up to your
camcorder or to a TV monitor.
Once you’re sure everything is wired correctly,
solder the 4 wires from the camera to the extension
cable (Figures G and H). I added a small piece of
electrical tape to insulate the 4 connections from
one another. Then slip the heat-shrink tubing over
your connections and use a heat gun, hair dryer, or
lighter to heat up the tubing until it becomes snug
(Figure I). If you use a lighter, quickly move it back
and forth under the tubing so you don’t burn it. Now
repeat the process with the other end of the cable.
