Just ordered a set today. Hope to have them installed by the next SF BayLEAFs meeting on November 12th. If it's easy, we might start offering it as a clinic--we already offer a horn upgrade/installation clinic at 3 out of our 4 rotating venues (one doesn't have a parking lot).

Couple of questions:
1. Did you need to raise up the car to do the work from below? Or can you loosen/remove the pan without jacking.
2. Could we just make a pig tail off the upgraded horn ground connection and use that? The 120 mA would be un-noticeable in the horn's 8-10 Amp circuit.

You likely could do it without jacking or ramps, but it is much easier with them because of the increased ground clearance. I did it using ramps.

Yes, that would work fine. I simply used a convenient body ground nearby each light but any ground anywhere will work.

I did mine a couple of days ago, Thanks GeekEV, with a few modifications. I routed the wires to between the grill and radiator and fished then using a wire hook. Worked fine. After one failure with the wire tap I chose to not tap the black/white wire. rather using an existing grounding screw. Works great and no crawling into the engine compartment. Smallish hands do help.

TomT-
1) So the above avoids running the black wire from the PDM or LCM?
2) Would you describe the location and wire you tapped for the power wire more precisely? Is that location better/easier?
3) What amber fog lights did you use and why? In a prior post you denigrated using amber over white.

Thanks.
 
1) Yes, that way you only need a hot (+12) wire. Plus, I wired the two hots together at one lamp (driver's side) so that left only one wire I had to run in to the engine compartment. You can pick up the ground for the lights near the lights, by tapping in to the horn ground or pretty much any other metal surface you like anywhere in the area. You could also tie the two grounds together at one light if you liked so you only had one wire to connect to ground. They will all work equally well for this purpose.

2) I'm not home so I'll have to look up the exact wire for you later but it was one of the switched 12 volt wires from the JB box. There are a number of them there that will all work equally well. It is hot whenever the car is in Run Mode.

3) Here is what I used: http://www.amazon.com/gp/product/B002E2WMWG" onclick="window.open(this.href);return false;. I like them because they have a deep yellow look which is best for fog lights (short wavelength light scatters more in fog than long wavelength light) and they also gave a nice contrasting look to all the other lights in front which are now cool white 6000K... Since I will be using them sparingly now that I have the LED DRLs, I wasn't concerned about power consumption any longer, and more about light quality and intensity.

Yes, that sounds good--it's only 120 mA total so there should be no stress running both lights through a single wire for much of the circuit. Good idea. I'm also interested in where you take off the +12V. And, does cutting a notch or drilling a hole in the "cover" for the Power Distribution Module compromise it in any way (e.g., water splashing up)?

My DRL kit should arrive on Wednesday...really like the look.

I shouldn't think so, particularly if you take care to only notch just enough to run the wire(s) through. But even water does get in there, the actual PDM board snaps in upside down so it would just drain harmlessly into (and out of) the bottom of the box.
 
I just did a mod to my LEAF where ONLY the LED headlights come on when the car is started and the marker lights are off. If the lights are in "auto"mode and it is daytime the LED lights are on but nothing else and the illumination in the car is normal for day. If it it is night then the marker lights come on and all lights will shut off after the car is off based on the auto timer. If the lights are in the off position the LED headlights come on in the day and go off once I turn the car off. I now have DRL on the main lights with no need to ever turn them on or off and they are only active in the day when the car is in the "start" mode. I may enhance this mod to include raising of the LED headlights in the day for better visibility and lowering them at night automatically.
 
Wow, that sounds elaborate. Did you actually do that or is this one of your jokes? It's hard to tell sometimes. :lol:
 
Agreed! But it clearly is another of his jokes... They DO have drugs these days that will help with his problem, by the way!

It's not a joke and it works great. Next I will enable this functionality to the fog lights once I change them to an LED I found so they will also follow the headlights as described. The mod is exactly what I wanted and is like a factory option.

Did you do a study to see which provides more visibility of the car from another driver's perspective? For example, the LED headlights are focused in the forward direction while the DRL's from the Superbright Kit look like they have a more dispersive lens/reflector on them.
 
That's a good question, though not one I really care about personally. Either is clearly better than nothing. And I like the look of the LEDs myself - ever since Audi started using them I thought they looked cool.
 
Nothing goes farther then the LED headlights and once they are tilted up for day use there is no way to miss the car. My point was not to create a cool look (although the lights tilted up do look cool) but to increase safety in the day. This is a big issue in some parts of the bay area. The DRL kit is low and does travel and command attention in the day like the headlights. Not to mention I did not need to buy or attach new lights and run a bunch of wires.
 
That is nearly the entire reason why I went with the LED DRLs: the look. The safety aspect was strictly secondary for me.

When the headlights and fogs are matched and the headlights are repositioned far above the stock position they look very nice. How about an LED light bar on the roof? :lol: I have not seen any LEAFs lit under the car yet :shock:
 
I have completed a mod that is similar to EVDriver's. When the car is in Ready mode, It enables the LED low beams and fog lights (with H11 LED's in them), and also tilts the low beams up automatically, so the car is more visible. When on auto and it gets dark, they automatically tilt back down and the rest of the marker/tail lights are enabled. If you manually turn on the park lights, the DRL's shut off, even if the ignition is on.

I'll try to shoot some decent pictures soon.

My goal is to make this mod plug-and-play, so as soon as I figure it out, I'll let everyone know.

Anyone know if the dealer can turn on DRLs as a software option? Some contries require DRLs (Canada). In my ICE the dealer just selected them as a configuration option. The LEDs look better, but this wouldn't requirewiring taps.
