NO! Never illuminate both filaments in single bulb headlamps. It overheats the bulb and housing. I have been told it can cause bulb to burst although I have never seen it happen. If the headlamps had seperate high/low bulbs as in dual headlights on old Chev P/U you can do it on them.
BTW... DRL Relay to Low Headlamp Relay jumper w/diode works great. My truck has been that way 3+ years.
