93-97 Formula Headlight Upgrades?
Are there any upgrades that are a low budget and close to plug and play?
Otherwise, you can get a pre-built HID Projector kit or make your own.
There are some newer sealed all-in-one LED housings as well of various quality. The prices of these have come down quite a bit and the quality has gone up quite a bit to the point that some of the ones on the market should be the top choice to look at. Just avoid the knock-off crap ones (videos below to help).
Looks like the 1993-1997 Firebird uses a 4x6 headlight. Make sure the replacement housings use a dual filament bulb (if Halogen), or Bi-Xenon Projector (if HID Projector) or Bi-LED (if Sealed LED Housings) so you keep the High/Low beam functionality,
The Retrofit Source has some options and you can find similar ones on ebay and elsewhere (of varying quality).
Also, If I remember correctly, the "Holley" LED Housings are actually Morimoto (which is owned by The Retrofit Source).
These videos may help:
I have no affiliation with any companies or brands listed in this post. I just found some neat stuff and want to pass it on to others.
