Thanks for the advise Kodiak,
I actually decided to have a look on the relay panel and immediately realized it is a very easy mod to do - all that was necessary was to ensure headlights relay gets power wherever ignition is on (to ensure headlights work only when ignition is on) and make ground permanent (to bypass headlight switch off position). In just about 10 minutes I had perfectly working up-to-code DRL-s on the car - only headlights are on when headlight switch on off position - no marker lights/taillights or instrument panel lights. I am happyWaiting for "form 1" to arrive in mail and go get it certified.
