Repair & Maintenance 2000 Rancher 350 headlights June 7, 2015 Sometime when I turn on the brights, the headlights turn off. Can anyone give me some advice on what the problem could be? I was thinking the terminals could need cleaning. How hard is it to do that? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
