Wouldn't your DRLs provide the added visibility that you seek when the headlights are off? You could also run with the headlight switch in the first position, making your car much easier to see as mentioned below.

I live in the mountains, and we regularly see dense fog. I used the fog lights on my 997.1 on a regular basis. I was considering changing the bulbs in the fog lamps to a yellow color, which is far more effective for enhancing visibility than a white or bluish color. It always makes me cringe when people want their fog lights to match their headlights; they are unclear on the concept of fog lights.

Many European car manufacturers refer to the small, secondary lights on the front of the car as "city lights" or "running lights" as opposed to parking lights. The intended use for these lights is to provide illumination and allow others to see your car when driving in a well-lit, urban area at night. In these situations, full headlights are considered a nuisance and they are not necessary.

When parking on a dark, narrow street, the parking lights can be illuminated on the outboard side of the car using the light switch and the turn signal stalk. In this mode, the lights closest to the curb are not illuminated, and the lights closest to traffic are illuminated.

Help! My driver's side (RHD) DRL is suddenly not illuminating (EDIT:actually illuminating extremely dimly), but the same side "position light" works per normal when the parking lights or dipped beams are on.

Before taking it to my indy, any suggestions? Or am I faced with a $ replacement cost? (Googled and p/n should be 997631108402)

Thanks...

another vote for missing the 911SC fog lights. I also turned them to the sides as it made it easier to turn into my cul-de-sac. Also easier to see the right side of the road on dark nights

I have a similar issue, just the center strip led of my driver's position light is not working. Unfortunately on the 997.2 you have to remove the front bumper in order to replace anything on those lights, even if it's just a simple bulb.

Same thing on my new to me 2010 ….. DRL on driver’s side dead, but turn signal and above mentioned position light both work. Frustrated that it can only be accessed after bumper cover removal. I guess they think the LEDs will be so reliable that they won’t need to be touched….. continuing to search for info.

One thing to note, there are 2 failure points for that led strip. The led module for that strip which is the square looking piece on the back corner of the fog light, and then secondly whatever the electronics are inside the fog light to turn it on. On my light, that led module is actually working properly. I tested it by simply moving the module to the other fog light and it worked, so the led bulb did not fail. I was hoping it was just the led module because it's a cheap $30 piece.

Unfortunately in my case it was the electronics inside the light that failed and does not signal the module to turn on. So I have to replace the entire fog light assembly which is a ton more $.

Years ago when I ran a turbocharged 911SC I truly needed long range headlights. I did some novel wiring. I had an extra set of fog light lenses—the usual fluted fog light lenses on the Bosch lamps, and a set of clear true European driving lenses. During foggy times of the year I can the fluted lenses, and a dashboard switch had them running only when the low beans of my H1s were activated. In non-fog times, I substituted the driving lenses on the same Bosch fog lens housings, but flipped a switch so that they would go on when the highs were put on.

The 997 headlights have evolved away from DLs.

So the module is connected to the car/wiring/plug? It isn't clear since you say that when you moved the module, the light worked.....

See below, that's the led bulb module for the center strip, it's screwed into the back of the fog light. You see the connection point at the top, the connector that plugs in there comes from inside the fog light, I just swapped it to the other fog light and it worked. So something of the wiring from inside the fog light is what failed on mine.

center strip not working on mine either… did you have to replace the whole light?

Rhern213

Yes I had to replace the whole fog light. The LEDs were working fine so there was something else that got damaged internally that wasn't turning them on.
