Buy a $6-15 Volts/Ohms Multi-Meter at your local Hardware store, Home Improvement store, or WalMart type store. Test your Jeep for 12 volts and for ground continuity. Start at the headlight plugs, then check the relay, then check the high beam switch.
If everything check good, test the headlights with 12 volts applied directly to the pins.
