Can anyone tell me how to modify my '07 Outback so that the foglights stay on with the high beams? |
high beams on, because when they are, the reflection back off the water
droplets is worse than when the light beams are at a lower level. So
why do you want to do this?

Don't know the answer, but to see in foggy weather, you don't want the high beams on, because when they are, the reflection back off the water droplets is worse than when the light beams are at a lower level.

Annoyingly, with proper fog lights, you don't even want the regular
headlamps on either, but many American car designs and jurisdictions
seem to disallow that. (Many seem to be white instead of yellow, too.)
Frankly, I get the impression that they're there for reasons other than
actually performing well in fog. Here in Ohio we're full of idiots who
like to drive around in regular visibility with their fog lights on. ):

Got the same problem here too, Mark. You dim your lights, and the oncoming truck or similar SUV dims theirs also, only to have a plethora of small driving lights come on. I'm not sure that is any better than just staring down two bright lights! And yup, always in the regular visibility! ~Brian "Mark T.B.

rated amperage capacity of the lighting circuit. Such a mod would
require beefing up wiring sizes and fuses, in addition to reworking the
switching.
I've found that here in upstate NY, where we're overrun with whitetail
deer that pose a constant threat to motorists, the foglights project a
short wide beam that illuminates the sides of the road better than
high or low beams alone, enabling a split second more reaction time to
avoid the deer or other critters that linger along the side of the road
just before they jump out in front of you...not really what the fog
lites were designed for, but it helps. That's the only reason I've run
with them on during conditions of normal visibility.

draw about 45 watts while high beam bulbs are about 55 watts. Since
the low beam setup is to run the low beams and the fog lights -
probably in the order of 100 watts, i'd be surprised if it required
such an upgrade to run an extra 10 watts.

Chicobiker Adds about 2 amps to what is normally a 10 or 15 amp circuit...a significant load increase. |
MAKE THE CHANGE AT THE RELAY. NO ADDED ELECTRICAL DRAW ON ANY CIRCUIT,
OTHER THAN WHAT WAS DESIGNED AT THE FACTORY.

I've often wanted this too -- not for fog at all (I try to just *stay
home* if it's foggy), but just for improved illumination of the universe
when driving on dark narrow forest roads and watching out for dark
narrow forest creatures.
More seeing is good. I actually wouldn't mind one of those crazy racks
of rally lights on the roof...
