H4 HIDs would have improper optics and would scatter light all over the place.

You'll need a proper DOT approved projector housing retrofitted into a 6054 sealed beam housing... Even then it'd be of questionable legality because the RX-7 did not originally come with the option of HID lights, so any kit that makes a HID bulb fit into a Halogen housing would be illegal and completely unsafe.

Thank you Pele you beat me to it.

Believe it or not you will get better vision with your stock lights than these cheap lights. Don't use fog lights during clear weather either.

Although I feel the same way, I have opted to keep my mouth shut about specifically mentioning them as forum sponsors and/or relating them to makers of such kits since I don't want to get banned from the site permanently. Since this site is without a doubt purely a business now, I've been awfully careful.

I choose to speak generically about the "HID kits" out there and let people come to their own conclusions about which company to choose.

99% of kits now days are illegal and result in worse lighting.

I did not know any of this. Thanks for all your input and am going to steer clear of cheap HID conversions.

Since I cannot afford/would rather spend money elsewhere a proper HID installation what would you recommend me do to increase my night driving visibility?

A higher amp alternator would help. A series 5 alternator would slightly increase the electrical output and result in a little bit brighter headlights without purchasing anything more than the alternator. An FD alternator is ideal but you'll need a pulley and special bracket to retrofit it onto an FD. Either the s5 or FD alternator requires a simple wiring modification that even someone with little to no electrical experience can undertake in an hour. Look at the FC Archive for a thread on how to do this.

The other recommendation is buying a Sylvania Halogen replacement bulb / housing. http://www.sylvania.com/ConsumerProd...en/default.htm These items can be bought for ~$30 at any local auto parts store.

I have a series 5 alternator and Sylvania Halogen Silverstar Ultras and I'm still not happy with my light output. One day I'll undertake the HID retrofit but until then there are only small gains to be made.

If you do intend to go with the FD alternator, PM Japan2LA with your requirements (single or dual alternator pulley) and he will set you up with everything you need to run it without under or overdrive.

They produce the maximum legal amount of light while staying within legal power consumption limits. They have colorless clear glass. Osram bought the well-established American lampmaker Sylvania in the early 1990s, so Osram is now Sylvania's parent company. Sylvania also sells a line of automotive bulbs they call "Silver Star", but it's not the same product. The Sylvania Silver Stars have blue glass. Light output is of legal levels, but as with all blue-filtered bulbs, you do not get more light from them. The Sylvania SilverStar bulbs have a very short lifetime, because the filament is overdriven to get a legal amount of light despite the blue glass.
To get the best possible seeing performance at night, don't choose extra-white bulbs.

He used to recommend the Sylvania Xtra Vision line of bulbs. They come in a pink and black package. It's what I use in halogen applications.

I think I've called them out with regards to providing a housing in their own section/threads... I'm not sure if I've bitched in the moderator's section yet...

Why don't we get sponsored by APC or a similar company that produces god aweful 10 ft tall wings, or something that is at least road legal and safe...
