1987 Toyota MR2 Headlights not working and need help asap

Electrical problem
1987 Toyota MR2 Front Wheel Drive Automatic

My headlights quit working and when I turn them on the headlights pop up like they should but they don't turn on and both of the turn signals light up on the dash. We changed the headlight relay and checked all the fuses but they still aren't working. Sometimes they work but 60 percent of the time they don't turn on. Any suggestions of what is wrong? I'd really appreciate it because this is my only car and I work night shifts and I can't drive at night with no headlights.
