Comparing 7" Aftermarket Headlights

Code Monkey

Observer
I've been a fan of LEDs for their advantages, but implementation and use have often left something to be desired.

In the motorcycle world there are some new lights that work well - at least as aux. lights, maybe as primaries - but in general they would probably not be good for night driving on public roads because their patterns would blind drivers coming from the other direction. They are not meant for use on public roads.

But the patterns I have seen on some of the motorcycle lights do indicate they would be good enough to use if you didn't have to worry about traffic - indeed some would be downright better than anything else I have seen.

HIDs seem to last on motorcycles until you take them off-road and then they start having problems. Not sure how they do on off-road trucks - maybe a better system than those sold for motorcycles.

I do know that the headlight on my dirt bike (it is plated and 'street legal') sucks big time so I need to get something better. It is rare that I ride it at night, but I have once or twice had to spend so much time on the trails that I've had to use the headlight to get home.

I think eventually LEDs will make their way into street vehicles and have satisfactory or better performance than what we have now - it will just take work by the manufacturers to figure out and implement something that works.

Part of the problem probably is that LEDs are fairly directional so they don't benefit much from a reflector behind them. The powerful LEDs are still very expensive so you can't just throw more of them in to get better fill - although that will probably be what they have to do.

cjlewis came over to the Hilldweller proving grounds with his Rubicon and set of Northridge-sourced IPF reflectors with clear bulbs. Big "thank you" to him.
The results were, ahem, illuminating.

These are wired with a pigtail connector rather than a full harness; they're fed stock PW-modulated power with added resistance from an extra connector.

These lights have been available from IPF/ARB for a long long time; they are very popular in the Land Rover community.
I've also made a large deal over the fact that IPF has never submitted them for testing to certify that they meet DOT or ECE regulations; we now know why.
Looking at Chris' Jeep from the side, I noticed that it looked like beams of light were shooting into the sky. So we measured it and, sure enough, we found 1700 LUX of stray light at a highly oblique angle (see photo). I measured my Cibie Z-Beams for comparison and got 63 LUX.
I can't imagine how these would work to mess with the driver's ability to see in fog, let alone oncoming traffic.
:eek:

The numbers:

Ambient temperature 53 degrees F; lens temperature 135 degrees F

Lowbeam value in blue, high in red.

LUX at 25 feet, sensor moved to highest output spot. 517/513

25 yards Right: 69/79 * Left: 1/1

50 yards Right: 2/25 * Left: 1/3

75 yards Right: 1/10 * Left: 1/4

Again, a big thanks to Chris for driving over from Roswell on a Sunday night and helping with this. It was a pleasure to meet him and I hope he'll join our camping group; seems like he and his family would really fit in.
Nice Rubi too...

Interesting. I have the IPF's in my 1960 Jeep run with upgraded wiring and never noticed that much light going upwards. I'd drag it out of the garage tonight and look some more but its raining :(

The IPF's were an amazing improvement over standard halogens. I'd love to try the cibies.

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.
My Unimog still has incandesant bulbs and a nice set of 24 volt fog lamps connected to work with my low beams. The led headlights will be a massive improvement over what I have and I have typically been an early adopter so it looks like there is a set of led headlamps in my troop carriers future.
I am sure that in a couple of years, led headlamps will be awesome but I have never been one to wait.:coffee: Just because they will be better next year doesn't mean I want to put my life on hold in the mean time.

If I had a Mog, Deuce, or dedicated trail rig, I'd probably keep these LEDs on it. They are incredibly robust and have plenty of light for slow-speed use ---- especially if they've got some help from supplemental lighting.

I still need to get a hold of some JWSpeaker 8700s (the cat's pajamas of LED headlights) and find a JK in the area with Deltas and stock lights.

I recently bought and installed some Roundeyes headlights and an aftermarket up-graded headlight wiring harness by Wired Wagon in my Land Cruiser.
Yeah, I know those lights. I'll have to rattle my memory but they're basically an off-brand 3rd-world product sold under a variety of labels. You could've gotten them for much less.
I'm pretty sure they're Chinese. Look at the KC version among others.

And I'm going to try out a set of JW Speaker model 8700s soon. I'm really excited; LEDs are awesome.

NOT as easy to install as the Truck-Lites at all.

Teaser shots of the JW Speaker 8700 LED headlights:

Your killing me...My local 4X4 dealer will be selling these soon.They are available in 24vdc so I really want to know what they are like.:coffee:
Iv'e put up with my current setup for years so waiting till the spring for a DOT approved LED option is liveable but you really should not tease me like this.

The sun is setting; I'll be out soon to check the spread and throw.

A big thank-you to Stumpy, Mrs Stumpy, baby Stumpette, and Stumpy's Garage for the right tool to put these dang things in. His cutting bit ate through the composite material in about a minute.

Some numbers for the JW Speaker model 8700 7" round LEDs:

Ambient temperature 55 degrees F; lens temperature 69 degrees F

Lowbeam value in blue, high in red.

LUX at 25 feet, sensor moved to highest output spot. 630/1139

25 yards Right: 48/86 * Left: 16/17

50 yards Right: 6/30 * Left: 1/5

75 yards Right: 1/9 * Left: 1/3

They were the brightest in the center of the road so far. Their distance and side illumination fall short of the Z-Beams though ----- but they're LED...
Foreground illumination to the sides is nil for 30 feet or so; strange artifacts in that area too, especially on highbeam.

But it all seems to work when you drive; I never got annoyed by any of it at all.

I like'em enough to keep them in and continue to shake them down for a while. I'll hit a few deer-infested dirt roads tomorrow early.

No problem, glad I could could help, ya big softie:

Definitely an interesting pattern.... I like them from the pics, except for such a dead zone on the initial/lower cut-off line. The fogs definitely help that though... How far off on the aiming were we? Those specs we used, 6'3", is that same process for any vehicle?

We were very off; you really need a flat white background and a level line.
6'3" is the fast-dirty-cheap aiming method for in the garage when you've got nothing else. 25' feet on a level surface is best for the amateur. And an aiming machine is the real way to do it.
I was shooting for a 2.5" drop at 25', give or take --- every set of lights has a sweet spot of its own.
I re-aimed last night before the shots and will tweak them on the wall at work after my drive in.

That shot with the baby is really something; she's so tiny and beautiful.
...and I need a haircut. I look like a hippie...

That was a fun commute to work.



I left earlier than usual so I could hit some podunk dirt roads.

And, right on cue, I had a big deer jump a fence and land ********** in the middle of the road in front of me. I saw it as made its leap and hit the brakes hard; got myself a little sideways and missed the beast by a good 15 feet.



I'd say the lights passed the test....



I got to the shop and adjusted the aim higher. The top LED is the lowbeam and I had them aimed thinking that the low LED did that duty. Should look even better tomorrow morning.
