Mine came with metal shields as shown in Carl's pictures. I removed the tip shield, held on by tiny screws, on one side only to see what difference it made... ZERO. The shield inside the H4 lens housing seems to accomplish the same thing, at least for the tip part of theHID bulb's shield. The rest of the shield may be needed - I didn't fuss with that.

Sorry this is just stupid - using high beams as low beams - just means using HIGH BEAMS ALL THE TIME...

This is not smart for you or for anyone else... don't mess with the lights if you don't know what you are doing - This is a safety issue for everyone.

Brighter is not better if it comes at someone else's expense - after all they they are driving towards you... and are now blinded...

Carl - 35w not 35amps (that would be spectacular!),

Nice for the H4's - Personally I recommend against putting HID in H5 lamps I think the results are far from acceptable (for others). It may be nice & bright - but the spill pattern is horrendous - the optics just aren't capable of controlling this much brightness.

You will get subjectively much better results for the driver with H4 lenses also. I realize the cost of the lenses is very significant - but they really are that much better.

I'm sorry. I thought he meant an led board that goes the width of the taillamps like modern cars. Those are replacement bulbs which I haven't seen light up as well as the normal bulbs.

Alan: the "I meant watt" when I wrote "amps" typo has been corrected:

All: we fitted that H4 bulb in a 928 here with 8" euro H4 headlamps and it dropped in perfectly. Photos were taken for the installation guide. The installation guide that shows how our product fits and the H4 installation is downloadable from our site. It is under the "Electrical Products" section toward the bottom: http://www.928motorsports.com/install.php

All: This morning I ordered in a small supply of 5000K bulbs in H4 and H5 formats. I will change the website to offer the consumer their choice of 8000K "cool white" or 4600K "warm white".

I'm curious about what others have done with their lighting upgrades. For those that went to the H4s, did you go with DOT lenses or E-code lenses?

Along with that, those that have upgraded to HID how was the light disbursement with your chosen lense type?

The ones I got for my Yamaha light up just as well as the original 27W incandescents, and with no heat. They also light instantly, which some studies have found makes a difference in reaction time for following drivers. Apparently your brain responds with less urgency to a signal that takes some milliseconds to build.

I've been running H4 (E-code) + 928SP's HID kit for about seven years. Nice to see 928MS offering these HID kits, as I don't believe that 928SP's kit is available anymore.

Light is definitely more scattered with the HIDs; this topic has been covered extensively in previous threads on the topic. IMHO, it's important to carefully align your headlights after switching to HID (and I'd strongly recommend H4s over H5s) and to be very conservative in your alignment. See the guide referenced in the first thread listed below for the alignment instructions I used and that have resulted in good results (I can count on one hand the number of times I've gotten the "turn off your high beams" flash in those seven years).

See the following threads:

• H4 HID Conversion Kit Installed; Writeup Now Available
• Anyone have more HID pics?
• Xenon/HID lights

FWIW, I'd recommend lower color temperatures over higher ones. Go with 5000 K (pretty neutral, similar to mid-day daylight) or below; you'll get more usable light. As a reference, tungsten lighting (the rather yellowish light you're used to from halogen and incandescent fixtures) tends to be more in the 3000 K range. The high temperature stuff is all about bling, and I've noticed that it even seems to be falling out of favor with that crowd.



Finally, regarding the discussion of LEDs for brakes, turn signals, etc., see the post My recommendations for exterior LED bulbs on '90 S4 (should mostly apply to '87+). I'll say no more here since it has little to do with 928MS HIDs.

+1 I bet that some who said the HID lights were up in the eyes of oncoming drivers just swapped bulbs but did not re-aim their headlights. As the bulb is longer, the reflective angle is different to the back, and that changes the aim on the road. Re-aim your headlights after installation, and lessen the problem a great deal. I aimed my H5 HID's, and nobody is flashing their lights at me. Pictures shown in the post #1 is H5 on low beam.

I also agree the topic of LED tailights is off-topic and belongs on its own thread.

Dealing with a shot radiator..didnt get to the bulb photo yet.

The SHAPE of the shield on the bulb made a HUGE HUGE difference on my H4 Euro lenses, huge difference.

I will get that..gah..as soon as im on the road again.

Alan

There are no stock H4 with DOT lenses, I severely doubt there are any aftermarket DOT approved H4's either.

All 928 Stock H4's are ecode - either 8" Bosch or 7" Bosch/Hella (& Cibies).

So that just leaves the H4 connector (not bulb) style 7" sealed beam units which are the crappiest 928 lighting option possible. Not H4's

No its about the optics - they aren't even very good with over spec wattage incandescent bulbs (~100W).

I'd say there is no way to aim these and avoid significant spill... perhaps people are just being kind for now - or you aim is compensated very low

Its almost impossible to tell how the nominal aim is with overspec H5's unless you have a DOT nub aimer... which will probably yield horribly bad results...

The focus point is wrong wrong wrong and never will be correct. You can re-aim till the cows come home but it is still wrong. More glare for other road users.
The high beam is just shifting the globe back and forth.

Now this glare may be good in a crap motor cycle head light as it gives a wider brighter light spread, so perhaps some safety benifit and i know because I have it in my bike until I find a better solution. The night lighting is awful too, but I hardly ride at night.

read the FAQ on this web site. It sells very good quality products and when i researched this some years ago was the best I could find.

With HID there are two sorts of units, reflector and projector. reflector is cheaper & not normally sold aftermarket and not as good as projector.

In Australia all HID must have automatic height adjust and lens cleaning fitted.
