Those are the ones. TxBenchracer put those on his '88 and they are fantastic. Makes H4's with big bulbs look dim and they don't blind anyone. I wish they were in 8" ones also.

Not a clear pic, sorry.

I found a couple of pictures of them that I took... Really interesting design.

I ended up ordering some replacement bulbs off of Amazon:


Worked out great ... thanks for all the advice guys!

Hi Harvey. For your next upgrade you may want to try these Super Bright CREE LED headlight bulbs. Fitted them to my S4 here in the UK and compared them to the Night breaker - see photo below. The night breaker bulb is on the left of the image and the CREE LED is on the right side as comparison!
I am now supplying these to the 928 owners if anyone is interested for the future upgrades.

How is the focus pattern and cutoff? that is the whole point of this discussion..

Brighter is NOT better unless the focus is maintained very well.

Even if these work well in H4 housings the results in H5 housings (USA) are most likely to be horrible (assuming 9004 style are even available) - becuase the H5 design is basically horrible anyway - even with a stock incandescent.

Hi Alan
Couldn't agree more. The pattern is well controlled by the H4 reflector and if anything it becomes well focused as a ball of light rather than getting scattered outside the preferred pattern zone on the road.
In the UK we have a MOT annual test which your car has to pass every year. This includes a Headlight check for scatter, focus and adjustment. I took my car down to our local station and they put it through the light box check, on the H4 scale pattern you could see that there was a focussing of the light intensity just below the horizontal pass line which was spot on and there was no scatter evident from the deflector. Obviously the way the light showed up on the test head box showed a different type of throw than a standard Halogen bulb with the same reflector but the light intensity from the CREE bulb was directed forward exactly where you wanted it ahead on the road and the pattern focus at the road side/kerb side to aid seeing the edge of a road was via the H4 reflector was equally intense & better than a Standard H4 Halogen bulb.

Remember in the photos I have a RHD car so the throw of the light is to the LEFT.

Good that you posted these - helpful particularly the last 4 - nice daytime white light.

The high beams look very good.

One notable: the LEDs low beams throw a lot of light on the road/roadside up close to car in the near distance Vs. the incandescents - subjectively this is not a good thing - our eyes adjust to total light and more light close up (inverse square law) means less good discrimination for light further away - even if there is still more light cast in the distance. The overall effect of this is hard to guage, but the effect tends to be worse for older eyes (as some of us can likely confirm).

It's impossible to tell how good the cut-off is on the low beams in this picture - hence the request for the pattern against a wall etc. It does seem there is more low beam scatter to the right here on the trees. I also note what appear to be some linearity differences - couple of horizontal bands across the road in the near distance - not so important - but the illumination of the distance markers also seems a bit uneven with 60 & 90 notably less bright than those around them.

Congrats for already doing a better job with these picture than most selling lights - meaningfull pictures - kudos!

PS The other thing to note is that this is only for H4 (9003) only - not for USA H5 (9004).

Hi Alan
Thanks for the comments. I do have the 9004 version available by order for the USA too!
The throw of light close to the car is actually visible from the Standard Halogen light as well in some of my other photos with different filters but the strength is not as strong as the CREE LED. I took over 30 shots of the lights on the road with different camera setting and filters in order to try to show the effect of the CREE LED lights but as you are aware, LED lights are very difficult to photograph as they show up completely differently through the camera lens. You may be able to see the same close halo of light shine close to the car by the Halogen on the photo below.
The Camera - as they say does lie! What you see with the Human light is much more impressive and much better to drive by than the standard Halogen bulbs.

The standard Halogen has an ark of light at the similar distance close to the car and then on the High beam photos the Standard Halogens have a hot spot focus about 10-12m away. The CREE LED's throw a lot of light out on to the road up to 100m in front of you and the light intensity in front of the car with both CREE Bulbs in the car is very uniform and provides a great uniform spread of light up onto the road. The driving experience in the dark is 200% better than driving with the standard Halogens or even the Phillips Ultra Extreme Halogen bulbs can provide.

As the saying goes - seeing with your own eye's is believing.
I was cautious previously when driving on country roads at night with my Previous Phillips Ultra Extreme bulbs- and these were the best Halogens I could find. The New CREE LED bulbs light up all of the road ahead both on dip beam and full beam.
