Enclosed Cargo Trailer | How to replace a light

Enclosed Cargo Trailers are useful for hauling all kinds of things including equipment, materials and furniture.  However, a bad trailer light could cause an accident or a law enforcement officer to pull you over and give you a citation.  Replacing a broken or burnt out cargo trailer light is not difficult and can be accomplished with a few simple hand tools and about 10 minutes.

1. Disconnect the trailer wire connection from the tow vehicle. You don’t want to short something out.
2. Use a screwdriver to remove the sealed oval light from the rubber grommet.  Normally this is a sealed unit that doesn’t allow for the light bulb to be replaced. 
3. Pull the oval light out and unplug the wire connections (push pin assembly).  Sometimes the wires are short, so don’t let the wires fall down in the rear wall space.   Replace the bad light with the new device and re-install the wires and light into the grommet.
4. Re-connect the wires to the vehicle and test the light functions using the vehicle.

Proper maintenance whether it is the electrical, bearings, tires or other special systems on your trailer will allow your trailering travels to be that of a joyful experience.

Tip: Trace the lighting wiring from the light all the way back to the wiring harness to make sure there are no tears in the wiring itself, thus insuring that it is actually the light that is bad and not something else.
