Hi all, after 2 weeks and 17 hours and only breaking one turn/tail light on a tree branch:ashamed:, I have moved the lights to the inside of the ROPS. I ordered 2 tuff light LEDs and plan on mounting them to the ROPS, using the bolt that holds the left side light on. I will use light angle iron with holes for the mounting (both on the left side, 1 rear, 1 forward facing). The lights I ordered have about 6 inch wires coming off of them and my question is this: can I just tap into the turn/tail light wiring to power the LEDs when the dash switch is on? If I can, do I need to add a resistor, and where to add it if so? I would prefer just tying into the current wiring rather than running new wiring for a quicker and cleaner install. TIA

What is the amperage requirement of your LEDs?

As long as the light circuit is properly fused now, if the LEDs draw too much the fuse will pop before you do any damage.

Thank you, They are 27 watt lights if that helps, not sure how to determine the amperage.

Look for the work light circuit on the tractor and tap into that. Most tractors have one. Sometimes the wiring is run to one of the rear fenders.

As s219 suggested a separate circuit would be ideal... I know on my older MF there is a work light wire on the left fender.

Thank you both, I will look into the tractor having an available worklight circuit, I'm going to stop at the dealer and look at a GC1720, with the factory worklight and see how that is wired/switched, etc. I would prefer not to have to drill into the dash to add a switch (but I ordered a harness and a waterproof switch with the lights in case I need it). I seem to recall from another thread that there is a white wire available under the seat for power.

ETA: and thanks for the link that conversion site is handy for many uses.

Stopped at the dealer and found that the factory, halogen work light is spliced right into the power line for the tail light. The factory one has a switch on the light itself.

Your factory work light circuit is just to the left of your top link pivot bracket when looking at the rear of tractor. It is tied to a factory wire or loom. I found it but need to pull it out because it looks like it is only one wire. Maybe there is two, or else you have to run seperate ground. Let us know when you dig into it further.

Installed them yesterday, holy c@#p are they bright, no issue working at night now. After talking to the tech at the dealer, who said it would not be an issue, I jumped them directly into the tail light circuit, yellow hot, brown ground. Had to look at the wires after the factory connector to get the right wires, as the wires change color at that point. I did it this way for ease/cleanliness of installation.

Looked at the manual today, it shows an extra power line for auxiliary right where and how Kevin said (1 hot wire).

If I need to add a secondary switch later it will be a 5 minute job. I'll give a shot to uploading pics when I get a chance but will make no promises. I mounted them using a piece of 1x1x1/8" aluminum angle, using the bolt that holds the taillight on, as I did not want to drill any extra holes in the ROPS.
