which are the most durable trailer lights?
The ones that are encased in a steel cage so I don't smash them with the riding lawnmower..
I've got optronic on one trailer, Wesbar on another, and cheap Peterson on a third.
They have all been in use for between 8 and 11 years, no issues.
Key to making lights function for many years is in the wiring.
Don't use the trailer as the ground. ! ! !
And don't use the hitch to ground the trailer to the tow vehicle. ! !
Run a ground wire from each light, connect it to the ground wire in the wiring harness connector. Use good wire 16-18 gauge. Not 20 or 22 gauge.
All connections should be coated, some use die-electric grease which is non-conductive.
I prefer to use OX-Gard, anti oxidant grease, that prevents corrosion BUT IS CONDUCTIVE.
Some people prefer to solder all connections.
After connections are made, they should be shrink wrapped with heat shrink tubing.
And all wires should be secured to prevent abrasions.
