For those of you that have converted to Xenons, 1) Are you happy with them 2) Which ones do you recommend as I noticed a few different makes available, and 3) Is the Install straightforward?

Thanks-

John

John,
So far I just replaced the H3's in my fog lamps with the kit from 928 Specialists. Easy as can be to change. Just remove the bulb, mount the ballast and igniter, wire tie up excess wire for a neat installation. I just had to break out the deflector inside the fog lamp because the Xenon bulb is longer.The results are awesome, I have been asked where I go them from all sorts of cars on the road. I will be changing the H5's in near future.

 

I just got my H4 HID Bi-Xenons a couple of days ago and plan on installing them tomorrow or Sunday. I'll post my evaluation shortly after the install.

 

Ed,
Any chance of taking" before" and "after" pics of the lighting to show the difference? Maybe a DIY write-up w/pics, a la Big Dave?
Glenn

 

The kit seems to be the same from several suppliers so my recomendation is to buy it from who supports you the best.

Click this link and you can see the xenons installed on my 83 US 928:

It's the second picture. They're much brighter than the OEM Halogens, the entire kit was like 40 bucks on ebay.

 

Hi m21sniper,

Lets please compare Apples to Apples, the kit you bought on Ebay is "simulated HID" bulbs, NOT real Xenon HID lamps with Ballast/ignitors.

From this Ebay auction (BTW, this one which looks just like yours and is $12.99, also pay close attention to the ridiculous $27+ shipping charge)

"HYPER-WHITE BULBS HAVE REAL XENON GAS INSIDE! ALONG WITH THE BLUE COLOR,THEY PRODUCE AN ARCTIC WHITE GLOW,SIMILAR TO HID,BUT AT A FRACTION OF THE COST! "

 

Those diamond cut driving lights = BLING BLING

 

Glen,
If you broke out the deflector in the fog lamp it isn't a fog lamp anymore right? its now some (possibly odd) driving lamp since it no longer has a low only cutoff....

Further - this comes on and stays on with low beam - even though it isn't anymore .... isn't this a problem? (maybe not for you but for the folks driving towards you?) Why not just put it in the driving light position only?

Also if the HID envelope is longer does that mean the center of the arc is in a different position than the bulb fiament was ... if so that would be a focus problem no?

Ed - I'd also like to see the before/after projection patterns (in fog/driving) in H4's. Ed - could you provide me a write up w/ photos on the HID install in H4's?.. be very interested...

"Lets please compare Apples to Apples, the kit you bought on Ebay is "simulated HID" bulbs, NOT real Xenon HID lamps with Ballast/ignitors."

Xenon and H.I.D are not the same thing.

The kit i bought uses Xenon gas filled bulbs, but does not feature H.I.D technology(nor does it feature the H.I.D pricetag either!). The 55w Xenon filled bulbs in the kit i used are MUCH brighter than the stock 55w OEM Halogen bulbs.

Simply converting to Xenon filled bulbs offers a huge improvement in visibility for a very modest investment.

H.I.D.s are even brighter, but they certainly are not inexpensive.

 

Alan,

I'm not Glen, but since I am the one that told Glen to bend or remove his reflector I will address your questions.

>If you broke out the deflector in the fog lamp it isn't a fog lamp anymore right?

Yes and no. In Glen's case he wanted to use his fog light as more of a driving light for his "high beams".

>its now some (possibly odd) driving lamp since it no longer has a low only cutoff....

Actually the fog lights use 2 or 3 different ways to create the effect they do (depending on US or Euro). Part of the fog light effect is the lens refractions which spread typically the beams wide and flat (euro Fog lens have less refractions in the lens but have a plastic inner refraction panel). The other part of the effect is the reflector which blocks the lamp from projecting straight out thru the center of the lens. This eliminates long range light from emanating from the fog light.

Removing the reflector makes the Fog light act as sort of both a fog and driving light as the lens still refracts the light flat, wide but now the center focus of the reflector also throws a large amount of light straight out acting as more like a driving light. As a matter of fact you can remove the reflector and inner refraction panel on a Euro fog light and it becomes a driving light.

ALSO, you DO NOT have to remove the reflector if you don't want to , but you will need to bend it down slightly to clear the longer bulb housing.

>Further - this comes on and stays on with low beam- even though it isn't anymore .... isn't this a problem? > (maybe not for you but for the folks driving towards you?)

Only if the Fog Light switch is depressed. Therefore you can leave your lights on low beam and when you want more stronger lighting you simply push the switch for the fog light instead of moving the stalk for the normal high beams

> Why not just put it in the driving light position only?

US spec 928 and 928s (80-86) do no have Driving lights like the Euros and some 78-79 US spec. 87 and later also have both fog and driving lights

>Also if the HID envelope is longer does that mean the center of the arc is in a different position than the bulb element was ... if so that would be a focus problem no?

The physical bulb is slightly larger, but the arc is pretty close to original position so it doesn't seem to be an issue.

>I'd also like to see the before/after projection patterns in fog/driving and in H5/H4's

Hi m21,

>Xenon and H.I.D are not the same thing

I know, but I think John was referring to the Zenon HID kits and i wanted to clarify this so people understand what the discussion is about.

This is a big confusion because of the loose term of "Xenon" being used by scam artists claiming and tricking people into thinking they are buying true Xenon HID lights. I don't want to see that happen here to my fellow 928ers.

In reality most of these so called "Xenon" bulbs sold on Ebay and elsewhere are simply halogen bulbs with a blue dichroic coating to make them look blue and fool unsuspecting people. As a long time entertainment lighting designer who has used, bought and sold millions of dollars of high tech lighting ( I have installed and used real HID bulbs bigger than my forearm) this is a pet peeve of mine. I meant no disrespect to the bulbs you bought.

 

Dave,
Thanks... Do you have a photo of the projection pattern on a wall? - were those H4's or H5's

Basically interested if the H4's knife edge is maintained well. Even if you don't have a photo maybe you can comment from what you've seen ? (if they were H4's of course...).

Alan

 

Wo worries Dave.

 

The photos on that thread were of H4s, if you notice even at that distance they do show just as defined a cutoff as the halogen H4s. Due to the intensity of the HIDs it looks fuzzier in the photo than in real life. My observation from driving with the H4 HID version in my Jeep Rubicon for a long time (durabilty testing on and off road before I would commit to selling these kits) that the HID H4s projected the similar pattern on the road as the normal H4 but due to the more intense illumination the cutoff and "kick up" was not as clearly defined as the normal H4.
