Here is an inexpensive 20 minute way to light up the rear work area of your TPH. I picked up a $6 35 watt utility light at my local COOP. There were already two holes drilled in the cross member of the ROPS. I believe these are for the mount of 1026"E" warning triangle(?). I drilled out one of the holes to mount the light, pinch tapped into the black wire to my ROPS lights and BINGO, I have a nice rear work light. It comes on when the light switch is in the last lights on position. I think John Deere is charging around $50 for a rear plastic utility light. The other nice thing about these generic work lights, they are housed in a rubber case. Nice protection for weather and wear

Hello Barry,

I love the ingenuity, but wish to point out that Deere does not recommend using a rear work light on the 1026R tractors with the optional forward lighting kit also. The reason is that there are already 4 lights on the circuit with the fender lights. This set-up would be acceptable with the 1023 but not the 1026.

Other guys that have the 1026 have plugged the rear light into the 12 volt outlet. Just wanted to throw that out there since I don't know if you were aware of that. I have been studying the electrical diagram and will probably add a separate circuit (or tap into the 12 volt outlet circuit) since I would like to have 2 rear lights in the future.

Thank you for the information. The John Deere Product Service Information, Installation Instructions, Titled, Auxilary Forward Lighting Kit, states in the first paragraph under Parts in Kit, "NOTE: Three work lamps can be installed on the machine. The auxiliary forward lighting kit contains two work lamps, and the rear work light kit contains one work lamp. The light switch cannot control more than three lamps." LVU15636 D4 (3/24/04) The rest of the instructions directs plugging the lamps into the purple and black wires of the harness. There is no mention of a separate wiring system for the 1026R Vs. the 1026E. Would you please post your reference where you cite John Deere does not recommend using a rear work light on the 1026R? Additionlly, the owner's manual says the Fuse-Fender lights (1026R only) and worklights (option) has a 20 amp fuse. The Light Switch fuse is 30 amp rated. I look forward to future clarification. Thanks

Well boys and girls, Mr. B certainly learned a lesson here - never post something as being a fact unless you also post your source of info along with it!!:slap-yourself-emoti

Barry, as you found out on the instruction sheet for the auxiliary forward lighting kit, it does indeed discuss the ability to use three lamps. This kit was originally designed long before the 1026R and its fender lights came along. The date on the printing, 3/24/04, indicates that Deere has not revised this publication, and we can only hope that they do so somebody does not inadvertently believe that they can do this based on how the current instructions are worded. I am posting the wiring diagram from the maintenance manual, plus where the build configurator says that the work light kit cannot be utilized with the forward lighting kit. Hopefully, this will clear up the mess that I made by not doing this originally.

The light switch has a 30 amp fuse, and then there is a separate 10 amp circuit coming off of it for the headlights, and a separate 20 amp circuit coming off it for the fender and forward lights. The 20 amp circuit CAN get over taxed by the use of the rear light on it since it is now powering five lamps.

Thank you Mr."B" for the information. I inspected the lights on my 1026R and here is the math for running the 5 lights on the tractor's 20 amp circuit. The two fender lights are each throwing 37.504 watts at 2.93 amps a light. The two ROPS mounted lights are each 50 watts at 4.166 amps a light. The rear light, I added, is 35 watts at 2.916 amps (John Deere's LVB2557rear light uses a 50 watt GE 887). The totals come out to: 210.008 watts/12 volts = a 17.500 amp draw on a 20 amp circuit. That leaves 2.5 unused amps on the circuit. I'm sure most electical applications like to see a bigger surplus margin, but the numbers do show it's in the operation limit of the rating. Jumping up to a 50 watt rear light would only leave a 1.24 surplus. I believe that is why John Deere doesn't want to recommend the extra rear light on the 2056R. Thank you again for your posting.
