Headlights high low beam and DRL lights?

For the car listed above GT 40th Anniversary edition:
Headlights:
Are the bulbs used the same for high beam, low beam and DRLs? Also, do I need to install separate bulbs for each? I. E. Do I install one set of bulbs for low beam, another separate set for high beam, and another separate set for DRLs? Or do I need just one set that adjusts for each function?
