Technically, yes. Should you? No.
mcnoople is right, non-factory HIDs are technically illegal, and it's largely because of folks slapping PnP HIDs in non-HID equipped housings (e.g. your OEM reflector housings). My experience (having had HIDs properly retrofitted into my headlights since... 2005), cops don't give a damn, so long as you're not blinding anyone.
Furthermore, you tell me which looks better, left or right?
The left is an example of what happens when you haphazardly put PnP HIDs in non-HID housings. The right is what it looks like when retrofitted.
I'm assuming the 92 civic has H4 bulbs as the high/low? If so, do yourself a favor and retrofit some Morimoto D2S
or Morimoto H1
projectors from theretrofitsource.com into your headlights. It's the easiest way to retrofit H4 headlights, and that method of retrofitting is reversible
. The big difference between H1 and D2S is the type of bulbs you'll be able to use. D2S is what factory HIDs can be (e.g. BMW, MB, Lexus) and you can get much higher quality bulbs. H1 is typically a bulb size for driving/fog lights. They'll have a nearly equivalent light output, though I've heard the H1 projector puts out slightly more. I can't verify that claim though.
I convinced a buddy (mind you, has no previous experience doing so) to do that HID retrofit, and I was there to assist/supervise his work. From start to finish (including removing his stock headlights), he had the retrofit done within 2 hours. We were taking our time and watching something on netflix while we were swapping in the projectors.
