Cost...<$1.00

Jump the #86 term from the parking light relay to #85 of the DRL relay. (Actually, the schematic is wrong and if you look at the bottom of the DRL relay it's actually #86. Doesn't matter anyway for this application).

Here's the pic of the jumper...Only draw back is unless you use another relay, your parking lights will be on when your DRLs are on and vice versa. Going the later route will be more involved.

The relays are a pain to lift. Use a flat blade screwdriver and GENTLY pry lose. Strip both ends of a wire and insert into terminals. Push in relay to hold in place.

#86/85 are low current terminals so you don't really need a really thick guage wire. Get one about 1/8" or so.

Pics with lights...

NSXTC, wow,
Looking good.
But do you mean that this way the parking lights and DRLs can and must only be on simultaneously? Driving by day AND night?
Solution would be then to turn off both during daylight. Especially where I live, because I get flashed often during the day by people who think I left my lights on unknowingly...
Thanks,

That is awesome. Thanks for the tip. I'll have it done before bedtime.

Already done. It occurs to me that I never use the parking light setting anyway, only the auto function. Forgot, I've got the Bosch off road lamps, too. I get so many people flashing me now thinking my brights are on. This'll be fun.

Yep. The parking lights and DRL will be on at the same time. Your right JCJ, you can simply turn off the DRLs in the daytime.

Forgot to mention that before removing the relays, pull the parking light and drl fuses (circled in red below) to prevent potential shorts caused by the flat blade screwdriver.

Once the jumper has been installed, put the fuses and relays back, but don't fully seat it until after verifying that the lights work. This way, it won't be too much of a pain removing the relays again.

great post

alright boys....

let me get this straight....

in auto function I will still have the DRLs?
in parkinglgts I will have just parking,DRLs and perimeter lighting??

in "on" all lights will be on?????

Is this right and if so...please tell me this is something that Hummer Girl can do????

If you can pry open a can of paint with a flat blade, you can do this. The hard part may be stripping the wires. That's the extend of the difficulty.

You are correct on all of the above questions.

Auto - Parking lights with DRLs during day. At night, DRLs, parking and head lights. You can also turn off the DRLs during the day which will also turn off the parking lights.

Parking - Parking lights with DRLs.

On - All lights

Perimeter lights - DRLs, parking, reverse lights

"Parking lights" being the front orange lights?
"Perimeter lights" being the combination of lights you can program to switch on when using keyless entry and remaining on when exiting for a certain amount of time?

I think I can do it...

I did this jump last night, and didn't drive it like that till tonight and it's great. I never realized how good the DRL's are because it was always light out. My better half was driving in front of me and says they're not too bright.

THANK YOU FOR THE AWESOME TIP. EVERYONE SHOULD KEEP 'EM COMING!

Parking lights are all the x-mas tree lights (i.e., front, rear, and running lights)

Perimeter lights are the DRL and reverse lights which you program using keyless.

NSXTC:

Great instrcutions and photos. I'll do this tonight.

Thank you

oh boy this was just toooo easy!!! The easiest thing yet I have done to this Rig!!!

How did you discover this technique to get the lights to do this?

Just curious to see if you are the brains of this operation.

The first thing was recognizing there are relays for DRLs and parking lights (this saved us a lot of time and $$). Next is to use a volt meter to find which terminal turns the parking relays on. Finally, use that same signal to power the DRL relay.

The tricky part was that the schematic is wrong for the DRLs. #86 is actually used for both relays, but the schematics listed the DRL as #85. I did this w/o the volt meter, but couldn't getting it working correctly. Only by using the volt meter was I able to find out where the problem was.

Well you did a great job in figuring it out!

I am very appreciative seeing that I don't see well at night and the lights on the H2 aren't the best I have driven yet at night.

My next step is to go to the Xenon White or Blue Bulbs.

Thanks NSXTC, My light project was finished 12/7/3. I went with the relay kit from RICKS that you suggested.($34.00) I hired a shop to help with the wiring because of my lack of knowledge and it took a while because they had never seen an H2 before. Anyway, I have the fexibility switching the DRL's on or off at anytime with the switch. It may not be a lot of light, but it helps and LOOKS good. Thank you..AL

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!

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."

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.

"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."

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.

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.
