Default Highbeams+Fogs.

I've noticed that when I switch from high to low, and I hold in the stalk, that the highbeams stay on and the fogs illuminate. Once I let-off on the stalk the lows turn on with fogs. If I hold in the stalk both the highs and the fogs stay on until I release the stalk.

How can I wire the lighting system on my Viggen to have the fogs stay on when I switch to highs?

I believe this is meant to prevent extended periods of use with high-beams and fogs, as this may overload the existing headlight wiring. A tech-2 could probably program it so this is possible, but I'd imagine you would want to re-wire the headlight/foglight harness with heavier gauge wire (and perhaps fuses) to prevent it from melting.

I found by holding the stalk both filiments in the main bulb stay on too.

I thought the wiring to the fogs and headlights is independent and through separate relay/switches. If this is true, and I am not saying it is, perhaps Saab purposely limited use of the fogs to when the lowbeams are on since it is always contraindicated to use highbeams in the fog?

I've read that it's illegal to run fogs and high beams at the same time. Though it seems unlikely that anyone would bother to pull you over for it unless they're looking for a reason to pull you over.

Also, I thought when you held the stalk back like that, it ran the highs and the lows at the same time, and maybe the fog lights as well. But I could certainly be wrong.

Tech-2 did it for me. Took my bud only a few minutes to do. (originally supposed to program the euro-city lights but I digress)


The dual-lit headlight filaments is something I posted about some time ago in my search for increased lighting.

It was suggested not to do it as it taxes the wiring big-time....
(more than my 85w low beams? )

..Its too bad aftermarket plug-and-play heavy duty headlight harnesses aren't available for more cars. Some friends have re-wired various cars' headlight harnesses for higher wattage bulbs, and it was a pain to do.

I'd consider it on the Saab, but I don't do enough dark countryside driving to necessitate it.

The big reason the highbeams and the fog lights don't run at the same time is because if it's foggy, the light from your highbeams will reflect right back in your face. Basically, the only real time you should be using one type of lights is exactly the time you wouldn't want to be using the other. Not that people don't like to drive with all of their lights blazing anyway...

While I totally agree with Jeremy that too many people use too many lights most of the time, I say get it done.

We are Saabers after all and not like the majority of people...

I live in the middle of absolutely nowhere, and drive home frequently in the pitch black with untamed dogs and deer constantly skirting around my headlights, and because of these roads I have learned four things.

One- Fog lights aren't just good for fog, they help you see into those hairpin corners earlier than the low or high beams.

Two- High beams help you see the deer sooner.

Three- Deer are a GREAT reason to see if your ABS still works

Four- The ABS on my car is kinda crummy.

However, the only ones we are concerned with are one and two (although free free to inquire about number four's backstory). ANYHOO, having both the high beams and fog lights would be a great advantage on deer-populated-hairpinny roads, but I agree with redrum and would be concerned about overloading the fuses and the wiring. And would probably want to bulk those up before having someone reprogram the car.

I just started to notice odd operation in my fog lights recently. I've had DRL disabled by tech 2 but I noticed when I have the head lights turned off and I signal, the corresponding fog light will turn on? i'm guessing its another tech 2 option? seems strange to me.

But when drivng at night with the foglights and headlights on, I like the extra light on the sides of the car made by the fogs. Illuminating the ground for a good foot on either side.

I am doing a lot of night driving on fairly sparce roads with lots of deer and coyotes, so I think I'll do it.

Thanks for the replies fellas!

SAP - I notice the same thing on my 99 9-3. I have long ago disabled the daytime driving lights by pulling the fuse, but when I signal w/out the headlights on the correspondling fog light comes on. I thought I had a wiring gremlin but now that I know someone else has the same issue I'm thinking it is working as designed.

Those aren't really the fog lights coming on, but a separate cornering light that's in each fog light housing. A lot of older American cars have them on the sides of the front bumper, and Saab put them in the fog lights of the 9-3 and 9-5 for the first couple of years.

I just checked this out on my '02 and I do not have this feature. I have the switch wired to the Euro setting and the #15 fuse is pulled, so I run the city lights constantly when the switch is set to off. With my turnsignals on, the foglights do not light up.

Do you know if that is a separate tech2 setting or is it supposed to be a function of the Euro lights setting?

I wish I could find a listing of tech2 settings so I could request what I want at my next oil change.

thanks for the explaination jeremy.

now after closer observations of the fogs i've noticed that the same thing happens when the headlight switch is turned to ON. so no matter the headlight selector position, 1 fog will come on when turning. Can this be turned off?

Saabsean - there is a list of tech 2 options on the saablink forums but the servers are down right now. i'll post the link later
