I've hooked up 3 -55 watt lights to that circuit, one rear facing,
the other two front, and have had no problems with fuses or lights dimming.
I don't know that the lights will dim immediately per se, but you should be careful with running them for too long if you still have the stock dynamo on your tractor. Each one of those lights will draw slightly more than 4.5 amps, so you won't have much headroom left on the dynamo (which is only rated at 14.5 charging amps.)
The reason why I bring this up is because if you're also running the head/tail lights at the same time, you'll be drawing another ~5.3 amps or so causing the battery to drain and potentially run down if left on too long. Just something to be aware of..
This was the primary reason I moved up to the 40-amp alternator given all the lights and accessories (including heat) I have on installed on my tractor for snowblowing in the winter.
