Low Beams and Highbeams both went out

If you lost both at the same time your probably looking at dimmer switch onfloor or headlight switch itself. The dimmer switch just because of it's location down on the floor is subject to abuse, check first there, pull the carpet back if you have to and make sure the connector is still tight, then if it is check for 12 volts with a meter if you don't have that you may be needing a headlight switch but also first there make sure the connector on the back of it is tight and not come loose
