The difference between low beam and high beam on ALL vehicles that have a separate bulb for low and high beam, is in the reflectors, not in the bulb.
If you find a way to fit a dual-beam bulb into a reflector that was meant for a single beam (either high or low), the beam pattern will not be correct for either high or low beam, and no amount of re-aiming can fix this situation properly.
The bulb and the reflectors are designed to work together, and if you put in something else, it will not work correctly. You might get it to function, but the beam patterns will not be correct.
Leave well enough alone.
