I just added lights and here are some pics.
NOTES:
1. I did drill and thread the lights into the ROPS. I accept it is not perfect but I don't accept it is a significant major risk.
2. I have not prettied up the wires yet. Too darned cold. I'll make them look nice and be protected in the spring, probably wrap them and make them match in color and run nice and straight.
3. The "bullet" connectors I got just came from the local hardware store. I also have bought huge packs of electrical connectors from harbor freight. If you can't find an exact match, cut the factory ones off and add an end you can get to the pigtails.
4. The new lights are AMAZING. I can swivel them and angle them. There is no need for the headlights really any more. I can aim one for and the other aft and work very easily at night.
5. I essentially ran one long wire from each side of the pigtail to the furthest light. As these 2 wires passed by the closer light, I ran them through a connector that has the two wires from the closer light in one side and the original 2 wires on the other. This connector closes around both wires like a clamshell and pierces the insulation.
6. I will protect all connections, but I can't find dielectric grease anywhere.
7. The lights run off the ignition switch and are on all the time. I plan to add an on/off switch right by the pigtails.
8. The lights are inside the ROPS or I'd break them off on tree branches. Also, they are placed so they don't hit the backhoe controls when the ROPS is folded down with the BH on the tractor.
The only problem I had was, because I'm a dope, I dropped one of the lights and broke it. I have to replace it now!!
