Yep, it's battery powered...... 4 AAs. Being in the NW we only use the boat at night for a couple of months in the summer. So I've never had to replace the batteries.
This solution worked great for me for several reasons.
- some drunk was bound to wipe out the stupid looking 6' stern light on the back (OK thats two reasons).
- Since it's above the bimini, no glare on the windshield.
- Take it down during the day. We ride a bit crazier than the average boarder sometimes, hot pickups, Around the Boats, etc. So if we can't take the light down, it's going to get broken off.
The figure 8 piece with a thumbscrew under it holding the light in place might be the best setup possible. Clean & removeable.
Heres a light at Overtons Or at Home Depot
