I really don't get it, guys. It may have been a stupid question but we've all asked stupid questions.

No it is a "WTF really?" question. Why have we all been wasting money on two ballast when we could have just bought one. Manufacturers are cheap, they want to produce the most product at the lowest price. I don't understand electronics all that well but I do understand that. Perhaps Ryan will come back and blow all of our minds, he knows a ****load more than I do about the measures of electricity. I just love when someone gets butthurt like this when they ask WTF really questions and get responses like these.

I gotcha. But I for one am actually curious as to why it is electrically impossible to run a couple of bulbs off of one ballast. I know it can't be done, but why? This thread has made me wonder.

they dont think it
its definitely not as simple as twisting some wires together 
we'd need to double the current from one ballast and then eletronics' main enemy...heat...comes in. you'd have to crank the input voltage (not feasible with 12.8-14.4v on tap...thats not enough swing)...or lower the internal resistance. how to do that?
decreased resistance creates more heat. heat reduces electronics life spans. people do "boost" ballasts, but they put a lot of heatsinking on them. i'd rather just put a ballast under each headlight and be done with it.
edit: so you'd end up with one ballast that's twice as big as single one, basically

Ok without being an electronics major (im an Emergency Science major) i cant give you the specifics or numbers or amps watts ect that the balast needs to run just one bulb..... but think.. try sucking a watermelon through a straw.. does it work???.. i dont think so.. or its a big Fuc#N straw
... you cant try and suck that much power out of one balast... Not only like i said its a wiring nightmare with big fire hazards 
... heres another example... Try and connect 5000watt subs to a 100watt max amp... (this is a real example from a hispanic's car that caught on fire.. he wasnt the smartest cookie in the box) Here comes shorting, high heat and fire.. Dude just get a second pair and hide the balasts for your Fogs in your bumper... Or go on ebay and get HID halogen knock off bulbs.. 8.00...

In the end, follow the manufacturer's instructions. They're tried and tested for a reason.
