Would be as illegal as all hell ( probably would get away with it down under ) - but from what little I know about lighting systems no small task to design and manufacture. Do you have the contacts/expertiese/engineering facilities available ???
Sounds good, but also veeeerrrrryyy costly......

Yeah, I went to art center in cali for industrail design. I can do molds and everything and i found the OEM company who made the headlights, and also the company who makes the interior instruments trying to turn those white/blue.
xenons dont work as high beams man. theres a reason they arent used.
few problems, 1. they take great abuse going on and off, meaning flipping them on and off as you often do with highbeams would be a nightmare on such expensive bulbs.
also they require a while to "warm up" anyone with the xenons can tell, when you turn it on, it isnt instant, again a problem for high beams.
to use xenons as high beams cars typicly reaim the low beam. the fx45 does this. the lens in the FX45 can be electonicly tilted to change the level of the light( a very cool feature that I urge you guys to check out) and also when you hit the brights, the lens flips up even farther to give a very long pattern of light but uses only one ballast that stays on.
if you could make THAT, where the lens angles to change the light angle, and then a " bright mode that raises it even more, that would be sweet, and Id imagine much less expensive than your proposed plan.

Bosch Litronic systems use only a single lamp also for high and low. The beam adjusting mechanism either uses a shutter style mechanism that creats a low beam cutoff point and/or actually moves the lamp in the reflector to change the focus of the optical system. Hella use a similar system.
As to start up, its hard on the lamps, but as high beam units they wouldnt have the same operating cycles as low so probably overall it wouldn't be the end of the earth. However the lamps do take time to hit full output and thats an issue that would tell against HID highs.

Yeah unfortunately this has all come up the past week and a hlaf about the HID as high beam. I have talked with hella in regards to a system that does two thing. One it angles left and right according to a turn, to light up the area usually unlit in the turn. and also will change angle for High beams seems as this is going to be costly though still researching...

Yeah, just gets more and more complex.....
Just as a "by the way" RHD beam pattern is opposite to LHD and as the beam pattern is formed by the PES rear reflector it suggests that for more than a US solution another set of PES reflectors would be needed ( although turning the LHD onee 180 degrees migh do the trick ) and we can't have "steerable headlamps" in Australia - Citroen tried it many years ago and had to disable it to get it accepted.

The only feasible modification would be to use a projector setup like that of the more exotic vehicles, where the HID bulb opens up a separate chamber (or actuates the bulb with a servo) to create a different lighting pattern. I know certain Porsches and BMW's do this.
Headlamp technology is definately advancing, although I am not too pleased with how complex some of the lamps are getting. Servos, auto-leveling devices, sensors, and tons of wiring -- to me, this just means more things to break and more things that require maintanance. Even WITH all this technology, cars like the new Range Rover STILL manage to blind the living **** out of me..
.. and yet, this is why I often times HATE technology and love simplicity.

Have seen HID H4 inserts with an inbuit solenoid that moves the lamp back and forward. there is also an extra reflector attached to the bulb that generates a low beam pattern.
But all in all we seem to be just about back where we started - do a HID low conversion if you need and perhaps a high powered H1/loom for high ( but don't melt the reflector ).

"Have seen HID H4 inserts with an inbuit solenoid that moves the lamp back and forward. there is also an extra reflector attached to the bulb that generates a low beam pattern."
Not exactly.. those solenoids change the beam pattern, but they are not true low/high beam patterns. A beam pattern is much too complex to be changed by a simple bulb with a solenoid unless of course, that headlamp is designed to work with that bulb -- if its a system, like some of the BMWs and Porsche's have.
So, even if you do shift the location of the bulb.. sure, it may look different.. if you want to try to "flash" other drivers.. or get their attention.. yeah, it may do that. But, the beam pattern will never really be one thats useable unless the headlight AND bulb were designed to work hand-in-hand.

Well hold on, thats exactly how a H4 insert does work. There's two fillaments - one ahead of the other ( and thats what the solenoid fakes by moving the discharge capsule ) and the extra reflector/ light barrier for the low beam filament creates the distinct low beam cutoff ( which is what the add reflector/barrier on the capsule does ) by blocking light from the bootom of the reflector which generates the high beam throw. And of course H4 does this with a single reflector.
So whilst there isn't the power of a second high beam lamp, it can and is done sucessfully. If thats a bit unclear Bosch publish the book "Automotive electrics and electronics" which has a better explanation of how the H4 generates its high/low and discussed movable HID in it s Automotive lighting section. Not a bad book for a whole range of high tech system explanations.
