360º Water Safety Light

These lights are intended for use on small water craft where local maritime regulations call for a fixed or flashing white light when you are on the water after sunset or before dawn OR when light conditions are otherwise low.

We suggest that you consult your local authorities about how to fix the light(s) to your boat to comply with regulations. Some may require you to fix a light to both the bow and the stern of your boat.

Combination Marine Navigation Light

These lights are intended for use on small powered water craft or sailing craft where local marine regulations call for port and starboard running lights and/or white stern light when your craft is underway. A 360º Light can be used in fixed mode as a mooring light.

The lights are intended for emergency or occassional use. The lights have been bench tested in continuous use for about 12 to 14 hours on the same set of Alkaline batteries. Your experience will vary according to how you use the light.

We suggest that you consult your local authorities about how to fix the light(s) to your boat to comply with regulations. Some may require you to use more than one light on your boat.

Care and Maintenance Tips for Lights

Maintaining a Watertight Seal

The lights are designed to be watertight by having a backplate with an "O" ring and seals around the retaining bolts and at the base of the hook. All three areas require maintenance to ensure the watertight seal is not compromised.

When changing batteries or otherwise removing the backplate.

  1. DO NOT use the hook to pull the backplate from the light. Place the blade of a screwdriver under the locator tabs to lever the backing plate from the light.
  2. Apply a smear of petroleum jelly to the "O" ring. This helps maintain the seal and also makes the back plate easier to remove and replace.
  3. Remove the retaining bolts completely from their holes and inspect the plastic seal for damage. Overtightening the bolts can result in damage to the seal.
  4. Inspect the hook retaining screw to ensure it is holding the hook in place correctly. If this screw is loose then the base of the hook seal can be compromised. Please read the notes below about using the hook.
  5. Dip the back plate retaining bolts in petroleum jelly before re-inserting them in place. This will line the thread of the bolt, the bolt shaft and under the bolt head to help maintain the seal. A smear of petroleum jelly over the top of the bolt head will also assist in maintaining a watertight condition.

Attaching to Your Boat

How you attach the light to your boat depends upon the design and usage of your boat. There are both a hook and a magnet built into the light that can be used or you can purchase tabs of 3M Dual Lock in our online store.

We offer some tips on using attaching options below.

1. Tips on Use of 3M Dual Lock
3M Dual Lock Specification Information

The 3M Product Specification Sheet details its full use and application, however it is important to note that it takes 20 minutes to cure to 50% adhesion, 24 hours to cure to 90% adhesion and 72 hours to cure to 100% adhesion.

Our customers have invented some ingenious ways to attach lights to their boat using 3M Dual Lock. Here is one way that might work for you.

  1. Use superglue to cement the hook in place and stop it from pulling away from the backplate
  2. Thoroughly clean the backplate with methylated spirits or an alchohol swab.
  3. Cut your 3M Dual Lock into 2 x 5cm tabs
  4. Split one of the tabs into two and trim off two corners as shown in the image below
  5. Apply your two split tabs parallel with the line created by the two backplate retaining bolts, one above and one below.
  6. Allow the adhesive between the 3M Dual Lock and the backplate time to cure. Maximum adhesion is only obtained after 72 hours.
  7. Attach the second 5cm tab of 3M Dual Lock to your boat ensuring that you clean the surface with methylated spirits or an alchohol swab.
  8. Allow the adhesive between the 3M Dual Lock and the surface you are attaching it to time to cure as above.
  9. Avoid using excessive force when removing your light from your boat

Remember it takes 72 hours to cure to 100% bond.
2. Tips on Use of the Hook

The hook on the backplate is designed for hanging the light in a suitable place but misuse can lead to the watertight seal between the hook and the backplate being compromised. We advocate a commonsense approach to usage and maintenance but here are a few tips.

3. Tips on Use of the Magnet

The magnet on the backplate is best used on painted steel surfaces.

As there are not usually many painted steel surfaces on small water craft this may not be an option for you. Some of our customers have fashioned mounting brackets that they fix to their boat and attach or detach their lights to the bracket using the magnet.
