I have done this mod and I like the look and the additional benefits of beeing seen earlier on the road.
Actually it is a quite simple mod,but only if you know what you have to do.
I installed the original Chrysler DRL module,but maybe you could also get an aftermarket solution. The original module uses the hgh beam at reduced intensity as the light source.
Firstly, you need the (original) daytime running light module which should be available at your dealer or you get one from the junkyard.They are all the same in all first gen LH cars.
Now you need the wiring schematics (which I could send you if you need them) to know the connector layout.
Finally you connect the DRL module to ground,power, highbeam filament ,lowbeam filament (to switch the drl module off when you turn your lows on) and ignition.
Furthermore you connect the drl module to the park brake lever switch .This makes the drl go on and off when you release or set the brake.
Huh....maybe not even that fast mod....but doable...
btw:IŽll try to get a pic of my DRLS
