Very clear and easy instructions. Great job. Even I figured it out as soon as I opened the fuse box. I stopped the task at the last minute because I wanted to think through 1/ if I want all the X'mas lights on during day driving, 2/ I can no longer use parking lites for longer period because DRL will be on too. 3/ other issues related specifically to my Hummer and usage.

B Moore, what do you mean: "I went with the relay kit from RICKS that you suggested.($34.00)" I read through NSXTC's posts several times but did not find such suggestion anywhere.

OK everyone, here's the cat's meow. I placed a diode, purchased at RadioShack, in line with the same wiring connection shown in the previous pictures posted by NSXTC. The diode allows current to flow only in one direction. Now my DRLs turn on with the parking lights, but the parking lights stay off during daylight hours. I checked the current across this connection with my voltmeter and it measures only 125mA, that's 0.125 Amps. I used a 200V 1A Silicon Diode from RadioShack (part No. 276-1102 "1N4003 Micromini Silicon Diode") and soldered it to the 20g wire I used. Covered the connections with heat shrink tubing. The diode only works in one direction, put it on backwards and it won't work. We'll see how long it lasts.

Nice touch Mango.

Actually where I live, having running lights on (meaning the rear brake lights as well) makes me more visible in morning/dusk fog where the sensor does not trigger the headlights. Also great for short tunnel pass.

Nice job Mango. I'll try it out this weekend.

I went and picked up the diode last night- I wanted to only have the DRL's during the day and everything at night.

Gonna try it out this weekend.

Great Job NSXTC...David I believe.

Lights work great as you speced...I will put in a switch whe the weather warms up.

Anyone know why there are 2 filaments in the DRL's?....I only get one light level...the lower one. How do we get the brighter one to light up?

Would it make a difference if the DRL bulbs would be pulled out, turned 180 degrees (along its length axis ) and plugged back in?

Which side would be anode side and which the kathode side? DRL vs Parklights.

To JCJ:

That would work if the bulb does not have offset guides, which most 2 element bulbs have so you can only stick them in one way.

I think the cathode side (side with bar marking) faces the parking light relay. Just turn on your headlights the make the connections temporarily and see what happens. When connected correctly, you can hear the DRL relay click on. Be careful not to let any exposed ends of your wires ground on anything!

This discussion group is really the best.

I already installed the jumper and will be getting the diode installed as soon as I get one.

Did anyone test the current (amps) on the DLR and xmas trees? The 1n4003 is only a 1Amp diode.

Just to make sure....I'll be putting in a 6amp 50 volt diode from www.mouser.com part# 583-6A05

Glenn, since we are crossing the switch side of the relay instead of the actual high current side, the current is very low. As I stated in my previous post, the current across the bridge between the 86 leads on the parking light and DRL relays is less than 1/3 of an amp. I used a 1 amp diode and mine is working fine.

I am beginning to think about replacing the DRLs with a fog light like the PIAA 540s. Mounting these is going to be the problem. I'm going to start a new thread on this topic.

I like the mod NSXTC has come up with but have one concern. Basically the DRL's will be like fog lights, meaning they can be on at night while your regular lighting is on. Where I live it is illegal to have fog lights on when your high beams are switched on. Example being in my wifes BMW when the fog lights and headlights are on while driving around and you turn on you high beams, the fog lights automatically turn off.

You should be able to do something similar to everyone else, except.....

Run the jumper with diode from the DLR relay to the headlamp low relay. (instead of from the parking lamps.)

connect the diode so that current is blocked from the DLR to the HDLP-LOW, but it allowed the other direction.

[Mango]

I measured the current from the 86 lead on the parking light relay to the 86 lead on the DRL relay with the parking lights and thus the DRLs activated. Diode was not in line yet.
