I’d recommend to install some really tough led lights because rocks and small bushes will destroy it really fast. Rigid industries makes some really tough lightbars, just check this small YouTube video to see it:

They come in different sizes and you can pick one for your atv or even a truck here: http://www.carid.com/rigid-industries/

There are water resistant Rigid Industries LED lightbars that are almost bullet proof, so you don’t have to worry about rocks mud or anything else on the trail.
