ok so im a cheap bastard who will think of anything to save money. im thinkin about investing in hids as many people on here have. i was thinking, the ballasts are there to send the proper amount of power to the bulb right? well what if i tapped a wire from the hid to the highbeam bulb and the fog light bulb? would it work? or would i short sumthing out? i've only workin on wiring a litle bit so im not sure and wanted to ask. but if it's possible then im goin to get hids this minute lol

 

I wouldn't mess around with that. Just spend a few bucks and get it done right.

You wouldn't be able to switch the highs and fogs off. I'm assuming you
intended to use HID bulbs in all places.

Think about it. If you spliced the wires from the ballast, then either there won't be enough voltage to start a reaction within the bulb (as the initial voltage spike is now split between 3 sets of bulbs) or once you flip on your lows; your lows, highs, and fogs would all be on at the same time. Best way to do that is get ballasts for all of them, buts its expensive and might not even work out right because the fogs and highs are reflector based (you need a specific kind of projector, like the OEM Valeos)and will cause insane amounts of glare if installed with HIDs.

 

That is a horrible idea. You'll blow your bulbs and/or your headlight wiring.

The HID ballasts step-down the wattage to 35 (from 55 or 65) and dramatically increase the voltage. Your standard wiring will not do this. Theoretically you can make your own balast but that is never suggested. In addition, inside the ballast, and sometimes outside, you will have an "ignitor" that temporarily spikes the voltage to ignite the electic arc inside the bulb; again, your standard wiring will never be able to do this.

Spend the $150-200 and buy a real kit. You can even buy some kits for less now I think. Check eBay.
