To make the lows stay on with the highs there are several ways to do it. Are you somewhat handy with wiring, or are you looking for a plug-and-play solution?
If you're handy, select one of the following:
1. Modify the headlight dimmer so that the constant power going TO the dimmer is tapped to the low beams. That way they are always on regardless of beam selection.
2. Add a relay. The high beams will turn it on and the power through the contacts will go to the low beams. When it's off the lows are on through the dimmer. Note: High beam goes to coil, battery goes to COM contact, low to NO contact. Ground other side of coil.
3. Find the stock High and Low relays. Add a medium-sized diode from the high beam coil to the low beam coil. The diode will let the lows be on without turning on the highs, but when the highs are on they will turn on the lows. (A diode is a one-way "valve" for electrons, and is therefore polarized.)
