I'm looking at about 175 bucks for a 4300K kit that includes a H/L Bi-Xenon HID Kit. Yes there's a lot of 'info' that comes up on the forum Search, but a lot of it is merely chit chat, etc. Dumb question: I am assuming that this H/L kit includes a HIGH and LOW beam bulb. Anybody have experience with H & L or just one bulb??? I will send the company an email tomorrow. The company is Genuine Design Lighting on Ebay - no affiliation. Thx

Can you get them with the ultra slim fit ballasts?

HID's for 993's are low beams only.

Marlon

Noah- these were a kit to replace an H1 system - don't the 993's have the H1 system? I didnot see a 993-specific kit. The ballast sizes were not specified either. There's a lot of these kits out there...

NP993

Yes, 993's use H1 bulbs. But again, the HID kits are only for the low beams. There have been a lot of threads on this.

You really wont need the high beams with the HID's

I put a set in my WRX and it made a HUUUUUGE difference

Marlon

OK - so what I'm hearing is that HID's are so good on LOW, that you never need to hit the HIGH. I'm thinking that with HID on LOW, you would not even SEE your lousy stock system on HIGH. Does that mean you CANNOT install a high/lo HID in the 993 - or merely that folks just have never done it and don't feel they have to with the better quality HID light???

Greg Bell

HID's are designed to work with projector, not reflector, beams which the 993 has on low beam. The high beam is reflector, and given the time it takes to fire up the HID's they are not suitable for high beams where you have a the ability to flash them.

Some systems get around this by having the high and low on at the same time and using a 'gate' to expose the high beams when needed but once again the high beam should be a projector beam.

Marlon

Greg - That makes total sense - thanks! I guess the high beam stays 'off' since they probably don't add much in the way of 'useable' light over and above the HID low beam??? As for 'flashing', can the crappy stock high beam even be seen by oncoming drivers?!?!

Marlon,
I have the factory Litronics (HID) and find that the high beams add very little usable light. The HID low beam light is very nice.

Cool - so I just order a single beam kit then. Prices seem kind of low 150 bucks or so? Is that a 'bargain' of sorts?

Marlon,
I have looked into HIDs for my 911 and have found the following: My car has H4s. When low beam is on, it's just low beam. When you select High beam, high beam comes on and the low beam goes out, so you are then driving with just High beam. HID H4s dual beams only have one HID globe but a "shade" is moved by a solenoid to change where the light pattern shines. i.e high or low.

My wife’s Astra has H1s. When she is on low beam, it's just low beam. When she selects High beam a separate light illuminates to produce High beam BUT her H1 low beams do not go out!

So we were going to get H1 low beam HIDs for her car because they are on all the time. HID highs are not that necessary for her because most of her miles are on freeways where she has lots of opposing traffic and has to be on low anyway.

I don’t know how 993 headlight work but I agree with the others when they say that Lows are all that you need.

Good luck.

Marlon

I'm sold - just going to come down to finding the kit with the smaller ballasts that can be tucked into the headlight bucket.

150 is actually kind of a high price. Search ebay. Shouldn't be more than 110-120 delivered.

Marlon

YES - you are right! The $175 price was for two bulbs per side setup. The single bulb systems are in the 129 or so range.
