Headlight Shootout

As many of you know, Truck-Lite was nice enough to send a set of their updated and improved LED headlights to 3 members of JEEPForum; I'll install mine tomorrow.

I've marked the exact location of the Jeep for reference. Please take note of what you can see off to the sides of the road as well as the FedEx boxes that I've used for markers. Our peripheral vision and the ability to see to the sides is what keeps Bambi off our hoods.

Round one in the war will feature the set of Cibie Z-Beams that I have now. They were purchased from Daniel Stern Lighting. The bulbs are Osram Rallye 70/65 and they are harnessed/relayed/plugged by Rallylights.


Markers are at 25yards L/R, 50 yards L/R, 75 yards L/R
Jeep is on the right side of a 2-lane road; camera on hood in front of driver

Ambient temperature 35 degrees F; lens temperature 157 degrees F at 6"

Lux readings Lowbeam/Highbeam:

25Right-65/ 49 * 25Left-11/ 5

50Right-4/ 29 * 50Left-3/ 4

75Right-1/ 17 * 75Left-0/ 5

25 feet dead center 583/ 970

Z-beams, lowbeam, with Osram bulbs.


Z-beams, highbeam, with Osram bulbs.

Looking forward to your review.

I'm looking forward to this as well! I am also hoping that you can do the same tests on stock lights and other lights as well, give a detailed yet dumbed down review (for those of us that don't have the grasp of lighting and laws that you do) and see it STICKIED!!! It really should be. I see these posts so often with no real results, all just personal feelings. I am glad to see the scientific method at work here. Puts a stop to many arguments. Good work and keep it up!

It was cold and windy and the markers kept falling down; my hands were so cold that I just ran back home...

Since I marked the test area, I can do a direct comparison with any light set-up.

Who's around Canton, GA that has a stock JK headlight system still and wants to drop by?
How about IPF or Delta?
I'll smoke some ribs...

I graduated the pic to make it easier to know the distances.

All of my LUX readings were taken at the exact same height on the markers to mitigate any advantages in beam placement. It would be easy to move the sensor around to find the sweet spot ---- but I figured that if a dog ran out in front of you, he wouldn't jump around to find your headlights' sweet spot...

The high value at 25 feet was in the sweet spot though. I just wanted maximum LUX and datalogged for about 3 minutes at high and low.
The Cibie surprised me by having such a bias toward center; proves that subjective impressions are worth what you pay for them.



BTW, as a point of reference, it was totally black out there. You can't see a single marker with the lights off.

after drivng with LED lights on other vehicles, i like my deltas more. the humvees out here suck. the light is patchwork and different on each humvee. maybe they are all installed wrong or not aligned properly. still the light isnt close to my deltas on my JK. plus the cost of those LED lights. vendors much think we **** gold with diamonds as nuts and corn.

cant see your picks. .mil networks block all free image hosting sites. jeepforum.com has attachments. they there forever and quicker than any free site for hosting images.

looks like you are heading in the right direction and taking your time. they may be better. will you be a Jeep Beach this year? I'd like to compare lights.

The Truck-Lites are installed.

As I suspected, they flicker when run with the supplied H13-H4 adapter. The Jeep's PWM cycles quickly enough that you don't notice it with a halogen bulb due to the physics of burning filaments. But the ultra-rapid start/stop capabilities of an LED causes them to respond to the pulses by an obvious flicker. It is much more noticeable on highbeam.

I removed the pigtails and used an auxiliary harness to provide power. It uses the passenger side stock H13 plug to trip a pair of Bosch relays and draws power directly from the battery. The power is clean and steady.

The Truck-Lites appear very robust and fit in the cans perfectly. Install took about 15 minutes; aiming was completely painless as well due to their dramatically sharp cut-off.

We'll see how they perform tonight.

The old ones were an atrocity and weren't worth considering.
I feel the same about Deltas, for that matter...

So far so good with the new set; no judgments until nightfall though.

No Jeep Beach for me; I lived in Florida for 20 years and had enough of it. I'll be roadtripping to CO/NM in May though and will post about the trip on Expedition Portal soon. We're going to have Little Guy Trailers build a custom teardrop for us and this will be the big shakedown trip for it.

My Conqueror will be for sale soon too (for anybody that's had their eye on it).

You should've stayed at work...

They were underwhelming. A definite improvement over the first incarnation but hardly worth the fanfare. I feel let down; I really wanted them to work well.

Ambient temperature 36 degrees F; lens temperature 48 degrees F (might have been engine heat actually).

Lowbeam value in blue, high in red.

LUX at 25 feet, sensor moved to highest output spot. 353/885

25 yards Right: 15/42 * Left: 3/5

50 yards Right: 1/9 * Left: 0/4

75 yards Right: 0/4 * Left: 0/3

Truck-Lite Lowbeam:


Truck-Lite Highbeam:


Close-up


Not so close-up


After gathering the numbers, I took a little spin on some dark twisty roads.
Long story short, I'll be de-installing them tomorrow and putting the Z-Beams back in.
They don't behave like headlights; they behave like a handful of flashlights.

Damn! I was sooo hoping these puppies would be great.
Bill, have seen the JW Speaker LED's in person?
A bunch more $$$ though.
Thanks for your quick turnaround on the review.

No ---- but I'd sure like to...

I was so attracted to the idea of not worrying about changing lightbulbs....


A volunteer from the audience stepped up and is coming over tomorrow; he's got IPFs installed and we're going to put them through the paces too. This really intrigues me since we all know there's never been any photometry released on them and they've never been "certified" by IPF to meet DOT or ECE regs.
Wonder if it's because there's too much light (glare/stray) or too little? Or are they just fine and IPF is just nuts?

Well I guess it will be awhile before I get to remove the 6 Mag Lights that are duct-taped into my grill
I was hoping this test would finalize my decision
So far we can't seem to get D/S off the top of my list.
