Polaris Sportsman 450 no lights?

I have an '06 sportsman 450. took it to repair shop for repairs, got it back fixed, but lights will not turn on. No Hi or Lo beams. I'm thinking when they took it apart and put it back together, they forgot to plug something back in. I searched the atv and followed the electrical wires coming from the headlights lights, but cannot find anything wrong. I have taillights, work lights, and instrument cluster lights, but no High or Lo beams. Any ideas?? Thank you.
