I think its a bad idea to install driving lights and use them as your primary light source. It would be like driving around with your high beams on all the time. You might be able to use fog lights because of the cutoff, but still a bad idea.
Its also a bad idea to use non DOT/SAE lamps, if you get into an accident at night its quite possible they may be used against you.
Retrofit some Hella 90mm modules in an call it a day. You keep your high and low beams, the lighting is good and they are legal.
