In California it is illegal to drive with the driving lights on and no headlights only at dusk or at night. During the day, you can drive with the driving lights on. You cannot drive with Amber or any other color without the headlights on. Fog lights, amber or yellow, cannot be used unless there is fog and the headlights have to be on.

I hope cops start stopping people who are using the blue lights who are wanna be Xenon light users. I hate the blue looking light on two lane highways...not pleasant to the eyes and mine are already bad enough!!

now when you put light selector into 'home' position your front fogs will light up when engine is working. 'home' function also works as usual when you shut down engine and fogs turn off in 30sec after you exit the car.

works fine.
Nice research. Wish I had known this before I purchased my module, as it appears to be a cheaper and easier way to implement the fog light DRL function on the 997.1. Thanks for sharing.

To those with a 997.2. The LED's in front can be programmed as DRL's. I did mine on my 09 through the PCM. My GTS came with them programmed to on. I think the tech at my dealership knew I had them set to on on my previous car and did the DRL's as a courtesy.

Sometimes I wish I could just turn them off. But they do give you a bit more visibility in traffic.

It's interesting when you think about when DRL's first began to show up on the road. The cars with their headlights on really stood out. Now with almost all cars equipped with DRL's it's not as big a hit visually.

I apologize if everyone else already knows this, but how do you pull out the light switch?

Thanks.

Here you go from macarbon website.

http://www.macarbon.com/install_guid...structions.pdf

After pushing in ****, rotate clockwise to the stop (about 1/8 of a turn). Keep rotated then pull outward and entire assembly will come out easily.

Those are not fog lights in the 997.2. They are just DRLs. Fog lights are high intensity, similar to headlight high beams that are projected from lower to the ground to cut under the fog and not reflect directly back at the driver. They are quasi high-beams for foggy conditions.

With the projected & masked xenons on the 997.2 cars, the quality of the lighting is such that fog lights are not necessary anymore for foggy conditions (I'm told), so they don't have fog-light options.

They may be illegal in some states; other states have not gotten around to addressing the specific issue.. .its the result of our patchwork of state and local laws concerning vehicle equipment and road use code.

The federal government is trying to address the issue:
Also, over the last three years, the number of glare complaints about fog and other auxiliary front-mounted lamps has increased substantially. This may be because of the significantly increased OEM installation of optional fog lamps and the similar increased aftermarket installations by the public on vehicles in use. This is accompanied by frequent misuse of these lamps: using fog lamps during conditions other than permitted by most states' laws. They are reported to be most often used at night in clear weather, and not under conditions of reduced visibility.

http://www.nhtsa.gov/cars/rules/rulings/glare.html
National Highway Traffic Safety Administration -49 CFR Part 571

The DoT of Oregon has this to say:
In normal visibility conditions, fog or auxiliary lights should be turned off.

Florida's law:
http://www.flsenate.gov/Laws/Statute...233 Spot lamps and auxiliary lamps.—

(1) SPOT LAMPS.—Any motor vehicle may be equipped with not to exceed two spot lamps and every lighted spot lamp shall be so aimed and used that no part of the high intensity portion of the beam will strike the windshield, or any windows, mirror, or occupant of another vehicle in use.
(2) FOG LAMPS.—Any motor vehicle may be equipped with not to exceed two fog lamps mounted on the front at a height not less than 12 inches nor more than 30 inches above the level surface upon which the vehicle stands and so aimed that when the vehicle is not loaded none of the high intensity portion of the light to the left of the center of the vehicle shall at a distance of 25 feet ahead project higher than a level of 4 inches below the level of the center of the lamp from which it comes. Lighted fog lamps meeting the above requirements may be used with lower headlamp beams as specified in s. 316.237(1)(b).
(3) AUXILIARY PASSING LAMPS.—Any motor vehicle may be equipped with not to exceed two auxiliary passing lamps mounted on the front at a height not less than 24 inches nor more than 42 inches above the level surface upon which the vehicle stands. The provisions of s. 316.237 shall apply to any combination of headlamps and auxiliary passing lamps.
(4) AUXILIARY DRIVING LAMPS.—Any motor vehicle may be equipped with not to exceed two auxiliary driving lamps mounted on the front at a height not less than 16 inches nor more than 42 inches above the level surface upon which the vehicle stands. The provisions of s. 316.237 shall apply to any combination of headlamps and auxiliary driving lamps.
(5) VIOLATIONS.—A violation of this section is a noncriminal traffic infraction, punishable as a nonmoving violation as provided in chapter 318.
History.—s. 1, ch. 71-135; s. 183, ch. 99-248.

+1 . Agreed. To the OP (Paul), thanks for a great and easy alternative to the DRL DIY. Too bad for me this came out after I purchase the Dectane Module .

I'm making the "hack" this weekend. I'm fine with the Florida law since it says "may" & not "shall" be used with lower headlamp beams. If I get stopped I just won't use the Home setting again.

The whole purpose of DRL's is to provide visibility to other drivers, not to be a hit. They have been a requirement on new cars in Canada since the 80's.
