We stock a variety of of high-quality underwater boat lights from brands such as Bluefin LED, Hella Marine, Narva and others. Our range includes single, dual and colour-changing underwater lights, with a choice of bronze or aluminium housing. We also sell related accessories such as switches & junction boxes.
Night fishing with lights attracts zooplankton to the surface that are chasing the light source. The bait fish follow the zooplankton and then the game fish (which we’re chasing) follow the baitfish. Soon you have a lifecycle happening right before your very eyes.
The zooplankton is attracted to submerged green and white lights. Similarly, small flying bugs like the same colours so keep the lights submerged if you don’t want a swarm of them. Green is also a good colour in areas where the water clarity is poor. The green light will make the water appear cleaner and reflect less.
How to install underwater boat lights depends on factors such as:
Light housing and hull materials are important because some materials react badly to each other, especially when water is involved. For example, underwater lights with an aluminium housing often have a corrosion-resistant coating and can be installed on aluminium hulls but not hulls made of other metals or materials (like steel or fibreglass). Aluminium-housed lights are most suitable for boats with aluminium hulls that only spend hours or days in the water and are typically washed down between uses.
Underwater lights with a marine-grade bronze housing can usually be installed on hulls made of composite/GRP, timber or steel. The bronze base is more resistant to corrosion than aluminium when permanently submerged in water.
Generally speaking, smaller lights are usually installed on smaller boats, and some of these do not require holes to be cut into the hull below the water for electrical wiring. Some come with a mounting block to allow wiring to be run up the transom instead.
Some lights must only be installed below the waterline, as they are very bright and need to be water-cooled. These lights will overheat if installed above the waterline. Other lights however can be safely used above or below the waterline. Always read the Installation Instructions supplied with lights or check with the manufacturer.
Because any hole drilled below the waterline is an entry point for water, it is safest to get a qualified marine professional (such as a marine electrician or boat builder) to install underwater lights on your boat. Any task involving electrical wiring on your boat should always be undertaken by a marine electrician due to the dangers involved, & potential risk to life of incorrect wiring.
Installation instructions supplied with most underwater lights usually include the following:
If you have a larger vessel and want multiple underwater lights installed on it, consult the light manufacturer for the recommended spacing between them. Sometimes this information is in the Installation Manual.
Colours penetrate the water at different lengths. Red light can’t be seen past 5m, orange disappears at 10m, yellow is 20m, green is one of the longest at 30m, but blue is by far the furthest at 50m.
Yes, it is legal to install underwater lights on your boat in Australia, if installed correctly & do not interfere with the operation of other lights on your boat required for navigation & safety. Always check the boat lighting regulations for your State or Territory if you are unsure.
