I bought three sets of these bolt in LED lights:

Since I'm not interested in headlight wipers, it was a neat job to remove the headlight wiper assemblys and use the harness for each of them to wire in LED DRL lights in the plastic trim beneath the headlights. The passenger side wiper was a problem to remove and I wound up snipping the wiper shaft with a medium size pair of bolt cutters to speed removal. To mount the lights requires 13/32" holes, and in my case I mounted one of the LEDs in the hole used for the wiper, that one required a large washer.
I mounted all of the LEDs with 2 part epoxy so they wouldn't fall out.
The wiring was easy, Just connect the Red leads of the LEDs to the Yellow of the wiper harness. Connect the black leads of the LEDs to black of the harness. (Note that the red wire in the harness is not used). I used some shrink wrap and black tape to insulate and some tie wraps to secure.
Wiring in this fashion runs the DRL lights when the ignition switch is in the run position. The DRLs are fused with Fuse 38
With the DRL lights (6) on, the current draw is 6 AMPs. The LEDs are bright white, highly visible. The low beams and DRLs draw just under 20 AMPs.
The low beam circuit draws 14 AMPs
There's some questions:
Maybe a single LED would be OK for high visibility and cut the current requirement from 6 amps down to 2 Amps. (not to mention , save a few bucks)
Who knows how reliable these LEDs are and if they require a heat sink? The reliability of these devices installed in the plastic trim remains to be seen.
It would be easy to kill the DRL's when the headlights come on by installing a relay (coil) at each headlight harness and open the power to the DRLs with the switched contact (NC) in series with the wiper harness power lead (Yellow).
That would be easier and less messy than wiring to a dash switch.
and those 12 V single pole DC relays are cheaper than dirt and plentiful at the junk yards.
