Depends? How long you going to run your light and winch? I bought and installed this super bright 20 inch Back Oak Light bar, it's too bright for group rides, wish I would have bought two adjustable pod lights to light up the front side areas and a smaller light bar? Check out the club store for back up lights, plug and play, my kind of accessories!
I'm looking at the 52" across the front. It would be used every so often such as clean a deer or track after dark. Winch probably wont get used a ton either and in both cases the machine would be running.
