Has anyone tried the Eagle Lights LED Daymaker headlight conversion that is marketed to Harley owners?

Edgarr · Oct 2, 2017

The Eagle lights work great and fit in a 7" bucket. They are very expensive $500 +.

I use this one at under $18, and it works on a + ground.

The Eagle Iights is available on line for under a hundred.
If you buy it from Harley it's over 5 hun.

It appears that some of you may not realize that the Eagle Lights Daymaker is not a bulb but a complete 7" unit with it's own reflector.
Led bulbs will never work right until they make one where the light source is in the same location as an H4 bulb.
What I am hearing from Harley guys is that the Daymakers are great.
Edgarr answered my question as to whether they fit in a Norton shell.
Thanks to all.

Philips already does make an H4 LED retrofit bulb bulb that is properly engineered....but they are expensive at about $100 or so...

Hi
This seems to be a good solution.
I have not tried this yet, but I will. I have been driving a couple of years now with a H4
so called hi / low . It's not hi / low but more or less. So this looks good.

I have tried them, even got one to fit a 575 headlamp and they are as described with a good beam pattern but I bought them direct off Aliexpress. With my previous LED's I always failed the MOT beam pattern test but passed with these bulbs this year.

I bought one of the H4-substitute LED headlight bulbs with the cooling fan and separate ballast on Fleabay for about $70US. It is motorcyvcle specific and the LEDs are positioned to take advantage of a non-LED reflector. Works a treat.

I quoted the above simply to provide the URl, not to single out "kommando" as the sole responder to my query so everybody please feel free to comment.

Following along the various LED headlight threads, that span multiple years, we obviously see that technology marches on, which leads me to a question. In the past many of the LED lights from various vendors were rated at 8-9K lumens. I see that the Aliexpress bulb mentioned here is rated at 4k lumens. Is 4K lumens bright enough for a single headlight or is it half the intensity it should be? How might a 4k lumen bulb compare to the factory incandescent bulb fitted to a Commando?

To assemble a headlight system using this bulb, do you simply need a ubiquitous H4 reflector and when ordering at AliExpress check the H4 box where the "Color" option list is? Of course we all know it's not "color", but rather should labeled "reflector". Thank you.

H4 halogen is 1100 to 1500 lumens, so the LED is brighter as I can confirm, suspect the 4000 is inflated but not as inflated at the 8000 claim, but they do add the lumens together when ordering multiple bulbs so 2 bulbs at 4000 are advertised as 8000. Select White 4000LM H4 on the listing.

Help – I’m blinded by the light!

Above I cavalierly referred to a “ubiquitous H4 reflector” and now that I’m looking for one it seems there is considerably more to it than I originally thought. The Hella website link below lists 3 of them but doesn’t state what the difference is between them other than SAE/DOT and ECE. Note that the image at the left of the webpage can be clicked and there are a total of 3 images to be viewed there.

Then I looked at the link directly below and got even more confused by the blue image (click on it to enlarge), as the 2nd line in the image labeled “ECE Left Hand Drive” looks like what I’d want in the US (flair to the right to illuminate the ditch), but isn’t our driving referred to as right hand drive?

https://www.retrofitlab.com/blog/dot-vs-ece-beam-pattern/

Amazon has the Hella 002395991 listed, but an individual that purchased it says that its cut-off is for left side driving not right side driving.

https://www.amazon.com/HELLA-002395991-Type-Single-Headlamp/dp/B0002M9QJM

Is it the bulb, reflector, or both that create the cut-off?

Hopefully one of you experts can get me out of the H4 ditch and back on the main road. Would be very helpful if someone might have the correct Hella part number for the headlight shell I need. Thank you.

did it say, right hand drive or RHD (RIGHT HAND DIP)?

Headlamps refer to dipping patterns, which are typically due to the lens - not the bulb nor the reflector.

Headlamps for use in left-traffic countries have low-beam headlamps that "dip to the left" (confusingly LHD - which does NOT mean "left hand drive"); the light is distributed with a downward/leftward bias to show the driver the road and signs ahead without blinding oncoming traffic. Headlamps for right-traffic countries have low beams that "dip to the right", with most of their light directed downward/rightward.

Prefocus lens (neither left nor right dip)

WZ507 · Oct 6, 2017

I've looked at headlamp lenses all my life and never noticed the wedge shaped prism until you pointed it out. In general the nomenclature surrounding headlamp descriptions is a bit ambiguous, with the terms “drive”, “dip” and “lane” further obfuscating the situation in my mind. At any rate, I just looked at the headlight on my 1975 MKIII and my 1978 BMW R100S and they both appear as in your picture labeled LHD, with the wedge-shaped prism to the right when the headlight is viewed from the front, so until I hear otherwise will assume this is the correct pattern for US use. The headlight on my 1974 Commando is a Lucas and appears to be what you referred to as "prefocused" as the lens is uniform across the front as shown in your final image. Thanks again for the clarification.

Nater_Potater · Oct 6, 2017

The whole LHD/Left Hand Drive issue STILL catches me off guard! Dave/Gortnipper, thanks for the clarification.
As for the prefocused pattern, I can only assume that's what I'm running (I'll have to check this evening). Here, you can see the difference between the H4 halogen bulb, and an LED in the the same lens;

Halogen

LED

The high beam of the LED adds to the upper portion to the existing bump while keeping the low beam half, rather than switching between the two as the standard H4 does. This has the distinct advantage of keeping the low beam flare for barrow pit illumination.

My LED is now three years/~8,000 miles old, and still going strong. I love it!

The terms LHD and RHD should be used to determine steering side preference for side by side vehicles.
The terms left side traffic (LST) and right side traffic (RST) are better terms in this instance, and not so ambiguous.

APRRSV · Oct 6, 2017

I have always understood that "left hand drive" or "right hand drive" referred to automobiles; specifically, which side of the car the steering wheel was on.
