I have been waiting to post a reply to this topic because I wanted pics of my setup but when I went to take pics my flash wouldn't work. I will try again tommorrow.
I recently did the work light addition to my ct235 and can add a little advice here.
1. The factory light location which is right next to the tool box is too low for a light to be mounted if you want your light to shine on a tiller or snowblower. I tested mine in that location with both attachments and it is just too low and is blocked by too much of the implement. I higher light mounting location like on the roll bar is very beneficial because it gets that light shining down from above the implement a lot better.
2. The rear work light wiring is tied onto the same circuit as the rear tail lights. That is a 10 amp circuit. That means that if we use our old forumla of amps=watts/volts then if our tail lights are running about 20 watts each (which I don't know but it should be close) then a third or so of our available amperage is taken by tail lights. So to be on the safe side I would say to stick with a 65 watt (maybe 75 watt max) work light on the rear. I could figure out exactly what wattage we can run on the rear but haven't taken the time. Either way, only one light can be attached to that rear circuit if you run a halogen fixture. LED or HID are a different discussion.
3. The rear work light wiring is powered on whenever the key is on. In my opinion you need a separate switch on this circuit because there is really no point in running that light unless you need it.
4. For the front work lights I installed a relay to a switch in the dash. The switch is located in the recess by the key. I ran a fuse holder and a positive and negative off of the battery to power the lights. The fuse panel has a spare circuit worked into it. You need to remove the fuse panel, then carefully remove the fuse holder connectors from the back of the fuse panel. The top three all need to come out as one unit since they are one piece jumpered together to a keyed source. You can power your switch off of this spare circuit. Just solder your wire onto this spare spot once you get it out of the circuit block, then run to the switch, then to the relay. This way your front work lights are able to handle whatever wattage you want, and your fuse panel won't burn out because of over amperage.
I will take some pics of my front work light brackets that are bolted onto the loader frame and of my rear work light bracket. I blew snow tonight in pitch black darkness and it is literally a night and day difference. I have absolutely 0 lack of light to blow snow or do loader work at night. If anybody has any further questions about this feel free to email me or whatever. I would be happy to help talk you through your work light project.
I hope to get pics up tommorrow night.
