driving lights
I think the best setups have a relay in the circuit. Any tips out there?
Regarding mounting, if you take the bumper cover off, you'll find that the actual bumper structure is low, lower then it looks with the cover on, so that it lines up better with car bumpers. That means you can't simply bolt the lamps to the top of the bumper cover and have a rigid mount, you'd have to make a stiff bracket that attaches to the bumper tube itself and stands the lamp up above the cover. The mounts do need to be stiff, and they have to attached to the vehicle pretty rigidly to avoid allowing the lamp to dance and vibrate over bumps and stuff. That would let the beam pattern bounce all over the road, which is pretty annoying.
Also, keep in mind that bigger is better - the bigger the lamp's reflector is, the better the beam pattern that can be made from a given wattage of bulb. Given the size of the Aerostar as a whole, a medium to large lamp would look more proportionate. Oh, another thing - a round lamp will always produce a better long range beam pattern then a rectangular or otherwise odd-shaped lamp would.
Lastly, khantyranitar is right about relays and wiring the headlamps. You absolutely need a relay in the driving light circuit to make the wiring safe and to maximize the output of the lamps. And it's always a good idea to wire the headlights the same way, for the same reasons. The factory didn't because they cheaped out. But it's easy enough to rewire, in fact, there are even headlight rewire harness kits out there to make the conversion plug and play.
When I wired the light bar on my Mazda, I installed a 4-relay box on the core support that allowed me to relay the high, low, driving and fog lamps.
(more pics here: http://s19.photobucket.com/albums/b198/expjawa/323/ )The driving lights in the center are Hella FF1000s, with 130 bulbs in them (if you plan to run high-wattage bulbs, make sure your wiring is appropriate and your alternator is up to the task). The fogs are Hella 500s, with the stock 55W bulbs. With everything light up, I've got locomotive-like lighting
. Further info on lighting in general, read though www.danielsternlighting.com. For info on Hella products, as well as some handy wiring diagrams and info, go to www.rallylights.com.
If you can fab a good mount for a large light, and don't care as much for appearance, go for one of these:

Sure it's pricy, but you will not be disappointed with its performance. Just one of them lit up will make you wonder whether your regular high beams were on at all. The bonus is that it only needs 35 watts to run, instead of the 55 or 130 watts of the halogen lights.
I've replaced the lights in my Mustang with 200mm H4 housings that have been adapted to use D2S HID bulbs, and I don't even need fog lights anymore. I keep them aimed low so as not to offend drivers in front of me. Check out the pattern at my site:
geocities.com/eycchu
But if I had HID driving lights, I would aim them higher for the distance. But forget about them if there is even the slightest trace of fog in the air. The bluer color of the HID light will scatter a lot more than halogen lights.
If you can't afford HID lights, try to find driving lights that use H1 bulbs. They are much more efficient than the more common H3 bulbs, but they are very rare. Dan Stern might have a source.
By the way, it's true that the larger the reflector, the tighter the beam produced. But most of the time, even for driving lights, you need more than two very bright spots way ahead of you. That's why most light systems will have lenses that distribute the light into more usable patterns.
Also, more modern lamps use a smooth/clear lens and design the reflector to create the beam pattern. The FF1000 is a good example of this. This is a bit more efficient then making the reflector a simple parabola and fluting the lens to distribute the light, which was of course in turn better then just a clear lens over a parabolic reflector. That would yield the pair of bright spots way down range that you referred to. A well-designed beam pattern for a driving light should be wider then it is tall, and should blend one into the other for a fairly even distribution. A fog pattern will be very wide, but very short - around 300 ft or so. Not very useful at speed...

I didn't realize the FF1000 used H1 bulbs. Do you have pictures of their patterns you can show? I need something good that I can use as high beams on my Mustang. I am currently using something that has the homofocal style reflectors like those in the Hella FF lights, but not nearly as good. But I have limited space.
I just found out that the non-HID version Hella 4000 lights use H1. Most places have the kit of two lights and all accessories for about half the cost of one of the HID lights. And based on my own testing, a 100W H1 puts out about as much light as a 35W HID D2S in the same housing. So a pair of these driving lights should work very well, assuming you can find a good place to install them, and you run them with a good set of wires and relay. I was suggesting an HID for a dramatically different light.
Fog lights won't have the distance, but they still light up the sides of the road better than standard high/low beams or auxillary driving lights. Besides, almost all of them use H3 bulbs, so their outputs are not as bright comparitively.
(I love light talk)
But either way, the beam pattern will come as much or more so from the lamp as from the bulb, so a picture of the beam from an FF1000 won't be real relevant compared to whatever you've got on your car. Or were you thinking of putting FF1000s on the Mustang? How would you do that - they're a 7" diameter light. Actually, if its a new GT, they might fit pretty well in place of the stock fogs in the grill, but on any other car I can't think of were you'd put them.
On the Mazda I've shown above, I actually sometimes run the fogs along with the highs and driving lamps. Because the wide beam pattern does light up the side the road well, it gives the car nearly 180 degees of useful lighting. Not a bad thing when you're flinging your car down a twisty dirt road in the dark in the woods...
The 7" light would be too big to fit into the space available in the nose of an 87 Mustang. I might have to switch to the 5-1/4" round high beams that use H1 bulbs.
Taking this back to Aerostars, I should post the pictures of the light patterns of my van with the E-code H4 lights. They're still using 55/60W H4 bulbs, but they're plenty bright.
