According to the link posted, the best I can tell you need the following
1 headlight, which is NOT required for day use but still must be visable at all times from a distance no less than 61 ft.
1 red tail light that is NOT required for day use and must be visable at all times from a distance no less than 152ft
Flashers, turnsignals, and an SMV sign are NOT required.
White rear facing lights are NOT permited
And if you are towing an implement or machinery, it needs taillights, flashers, or reflectors even if they are visable on the tractor.
This is the nearest I can tell.
But for safteys sake, have headlights on regardless, have flashers on regardless, and have a SMV sign clearly displayed.
