I'm currently running hella e-codes with halogen bulbs, but thinking about a led bulb upgrade. diode dynamics is in earth city, might be worth a shot

Has anyone tried running HID or LED bulbs in the Cibie housings?
Yes. I'm running the Cibie 82440 light unit with HID and the beam pattern is not quite uniform. It does have a flat cut off so no blinding on coming traffic. Street and highway signs light up tremendously and compared with factory HID or LED headlights, this is much better for sign illumination. The only thing is the bulb is not optimized for this reflector / lens design and it has dark spots in the near field. No experience with LED bulbs in this lens.

Yeah, I'm asking as I'm currently running the Cibie's with Philips halogens in them and I'm wondering how HID's or LED's would work in the same housing. I know there's concerns about where on the bulb the light originates and which direction it's projected in to allow for the reflector to catch the light the most effectively.

Which is why you should not be running that bulb in that housing. It is designed for an H4 bulb only. The dark spots are because the filament is not in the correct space for the optics of the lamp.

The Cibie lens was designed for halogen and will work best with a halogen bulb. You might want to try some of the high output halogen bulbs by Phillips and see how that works.

For HID or LED bulbs, it will be less than optimal as the light source point of origination will be different than halogen and you will get uneven light pattern. As I mentioned, with a HID bulb, there is a dark spot in the near field but that doesn't bother me as much since I've gained significant light output to the side for roadside sign illumination.

Of course. That was what I expected going into this experiment. Never the less, short of building my own custom HID lens assembly, this current light pattern with the Cibie unit meets my objective. This combination is significantly brighter than what Jeep puts on the JLs and JTs with their projector LEDs. The factory projector LEDs have a uniform beam pattern but they do not light up road signs very well. I've driven with the factory projector LEDs and they don't even come close even with the shortcoming that I mentioned above.

Because the road signs are above the cutoff. A proper H4 pattern is horizontal to the left and angles up to the right to provide illumination to road signs.

Yes. Of course! Just want to point that out to the community as many think just because the headlight is LED or HID or the lens is projector that the beam pattern is great down the road. The US has not caught up to European lighting standards.

And in Europe, overhead road signs are all lighted. It would be nice. US regs require a certain amount of the light to go up on low beam for that reason.

The US lighting regulations are pathetic. What you say is true but if there are signs that are overhead, such as by an overpass, they usually have their own independent lighting source. Our US headlights are very very poor when it comes to illuminating street side signs. All you have to do is to look at the beam pattern from an European lens and an US lens and it would be obvious.

The proper way to use the Cibie or Hella buckets is to add the Rally Lights relay harness that eliminates the PWM signal sent to our headlights. The PWM signal effectively reduces the voltage seen by the lamp. The harness gets you full voltage which increases output by around 10-15%.

Then you can safely (electrically) add the illegal (not as safe) high wattage halogen bulbs without risking wiring failure.

That's a solid performing system. But I'd still take my Pro Comp LED's.

Philips created an LED bulb to be used in H4 buckets, but they are expensive. Not worth the $$$.

That is what I am running in her '15 JKUR. For my 09, I cobbled together a systems using a cheap ebay H4 booster with a truk-lite anti flicker harness. Works great til both low beams pop at the same time. Fog lights were working but I decided that I would get pulled over if I tried to get home like that. Only lost one screw swapping bulbs in the Walmart parking lot so I could see to get home

Yes, the drawback is the lamp life expectancy is reduced significantly... Back to old school replacement every year.

This is the Philips LED lamp that does pretty well in the halogen buckets. Although the one you listed is interesting too, I don't think I've seen that one...

Actually about two years.

It's still $175. I have less than that spent on my whole system.
