Now Louise...you need to replace the DRL's with a real fixture, not just the night-light factory bulb/fixture.
I replaced mine with '03 Lincoln Navigator fog light fixtures, and a 9005 bulb. Aimed them down a bit and they are "great"!! I did the jumper without the diode...if I don't want them on in the daytime, I just flick the headlight switch off.
