BAA stocks submersible LED trailer lights – separately (left or right lights), in twin packs (both left and right lights) or kits (including a license plate light, pre-wired with cable and sometimes with multiple plug options). We also sell LED licence plate lights and LED trailer board lights. Brands in our range include Narva, Roadvision, AXIS & Easterner.
There can be several reasons why your boat trailer lights fail. The obvious one is corrosion - saltwater and wiring don’t mix. Once the wiring is several years old, it can start to corrode, particularly if there are several joins. There may be corrosion where the wiring connects to the lights when you remove the plastic housing. The plug may also have some corrosion or just be dirty and in need of a good clean.
If you’ve owned a boat for any length of time, you will know that your boat trailer and its lights need regular testing and maintenance. Firstly, you need to check all the lights are working every time you hitch the trailer to your car. The lights & wiring also need regular maintenance. Every six months, take a close look at the wiring, make sure it isn’t cracked, none of the lenses have been damaged and the lamps are working fine. Also, check the reflectors on your trailer are still attached and in working order.
In Australia it’s a legal requirement for your boat trailer to have working lights no matter what time of day or night it’s on the road. Boat trailers can have detachable lights and wiring where they may be immersed in water and cause short-circuiting. However, most of the LED trailer lights sold today are fully sealed and watertight during submersion.
Manufacturers of trailer lights are responsible for making sure they comply with Australian standards, but trailer owners must ensure their lights are installed and maintained according to the manufacturer’s instructions.
Lights on trailers must operate with the corresponding lights on the towing vehicle. Lights on a trailer must not show red light to the front or white light at the rear except for the reversing light. The colours allowed for each light position and reflector are listed in the Australian Technical Requirements for trailers less than 4.5t.
Electrical wiring on trailers in Australia must be supported at 60 cm intervals, and:
be insulated at joints
be located where it can’t become overheated
not be in contact with any moving parts
be protected from chafing, and
have an earth return wire between the towing car and trailer
If you have any concerns about the wiring on your boat trailer, contact an auto electrician.
