to get the highs and lows on you want a brightbox:

But I'm not sure it's such a good idea cause it produces more heat in the headlight having both beams on. Here is Ford's bulliten for F-SD:

I did that mod to my truck as well. It is much brighter to have on the brights and the fogs at the same time. I recommend it to anyone.

 

I did that mod to my truck as well. It puts out a lot more light to have on the highs and the fogs on at the same time. I recommend it to anyone.

 

That's the way mine work, has to be, I don't have fog lights.

 

hmmmmm maybe I am seeing things. But it makes sense. When I hit my high beams pointing at a wall, it didn't look any brighter than using the flash to pass feature. Dang if I know. but I would like brighter, more covering lighting when I have the high beams on. Saftey is the most important. And seeing at night is sure safer. I just hope the lenses won't melt.

 

If you really want more light get some auxillary driving lights. I just put some PIAA 520s on mine and it is a lot brigter more focused beam than the brights. And its yellow so it cuts throught the rain and fog better (and looks cool).

 

Would there be a way to wire it up so a set of aux driving lights like those come on automatically when I turn the brights? I just hate having to hit a lot of buttons to turn it off/on when I see a car coming.

 

Im sure that there is a way to do it. I just kept mine on the button but its probly as easy as grounding it to the fuse the brights use so it becomes grounded when the brights come on and they come on as well. Anyone done this?

 

Ok, I think I know what your looking at. Before you did the mod so the fogs would stay on with the highs this is how they worked.
When you would use the flash to pass the highs and fogs would work at the same time but if you turned the highs on the fogs would go out. Now that you did the mod it's going to look the same no matter if it's on flash to pass or if the high beams are on. If you still want more light look into getting some auxiliary lights like O1COBRA suggested. I got a set of lights to add to mine as soon as I get my light bar painted.

 

I have my driving lights wired up this way. You can get some mini fuse taps to get power from the fuse box to activate a relay. This is how I had mine at first, not sure how well it works on the newer trucks. I now have a custom headlight harness (see other thread) and get my activation power from the original headlight harness. I just got a generic blade connector at the parts store and slid it into the plug (high beam slot). Now I can run just high beams or flip the switch and have driving lights too. Turn the brights off and the driving lights go out automatically.

If you are going with something for the high beams, make sure you get an actual "driving light" beam. Get some decent lights too, the cheapo lights won't put out half the light that a quality set will. My Hellas use the same bulb and wattage as my cheap Autozone set did, the difference is amazing though. Even though they have a broader spread, they are still brighter where they light.

I too was thinking that the highs and lows came on together on these for FTP mode, maybe not. It's not impossible just because it's the same bulb, my '99 works that way.

 

the high beams seem brighter in flash-to-pass mode regardless if the fogs work or not.
Does the high beam position use a voltage limiting circuit and can it be bypassed?

 

The flash to pass mode powers both the low beam filiment and the high beam filiment at the same time. Normally when you switch on the high beams the low beam filiment goes off. My wife drove my Bronco one time and held the flash to pass on for a long time. One of the bulbs overheated and shattered. The broken glass is still in the light housing because I didn't want to remove the entire housing to dump out the pieces.

 

Right, I was wrong. I tested it tonight .The flash to pass has them both working and if the fogs are on when using it you'll have all three working.

 

I'm looking to do this for my 2012 F250. This link no longer works. Is there a update link or something ??

 

Something else to say is do not PUT THE LARGE Hi intensity light bars on any truck.
They are unfocused and blind oncoming drivers no matter if mounted high or low.
If you use these, only off road.
On public highways they must be covered by law.
To brighten up a stock head light, look for bulbs that are speced about 25% brighter but still US DOT approved.
And yes, driving lights must not be uses with high beams on, by law again.
This is why they do not come form the factory with that function.
Good luck.
