Just picked up a 2007 honda rancher 400 trx with es. I noticed the left headlight was out when I bought it so I bought some new leds to brighten things up a bit. When I switch on the lights,only the right headlights illuminates and when I switch to brights only the left headlight illuminates. I switched out the handle bar switch assembly after taking apart the old one and not seeing any corrosion. Installed new switch assembly and same thing. I'm a bit stumped. Can anybody help or if someone who's experienced this issue could chime in?
