decent led headlamp diy for Puch

Not exactly drop in. Would be nice to find a really high performance 1156 LED true "drop in" but I haven't seen one yet

http://www.homedepot.com/p/Philips-50W-Equivalent-Bright-White-MR16-LED-Energy-Star-Light-Bulb-461509/207106557

If you cut a hole in the back of the light, the black plastic half of the assembly, exactly the diameter of the bulb just under the lip (the second widest point in the image above) when the bulb is dropped into that hole snugs against the glass reflector perfectly and concentrically when the reflector is screwed back on.

Direct wired to the harness it works wonderfully. The circuitry inside makes it flicker free, good light at idle, and very good light at speed. Nice spread angle looks natural as well.

Re: decent led headlamp diy for Puch

Interested to see how long it will last. If it truly drops in and wires up then it's already set up as a 12/6v DC bulb.

Most times with out external rectification these types of set ups only last so long.

Re: decent led headlamp diy for Puch

There are tons of 1156 LED bulbs out there with the right bayonet mount for moped headlights. There is not a ton of 1156 bulbs that actually PROJECT light effectively onto the road given the angle of moped headlight housing. After experimenting, I ultimately went back to an incandescent for the headlight. The regular bulbs are cheap and last forever. Very interested to see whether this bulb actually projects as well as a regular light would.

Larson LED headlights are awesome and have different beam angles to choose from.

...just an update. apologies to anyone who tried the bulb above. I didn't realize how bad it was until I used an improvement. It is Home Depot sku 1002 631 975.

620 lumens, 7.5watts, 3000K color. 35 degree spread. 9 bucks each.

The spread is important. A full 180 degree spread puts almost nothing down the road to see with. 35 degrees is quite nice with 620 lumens. My Newport stock magneto runs two bulbs just perfectly. At idle it dims a bit and has very slight blinking. The MR16 bulbs have all the internal circuitry necessary to take the ragged 3 to 18 volts ac coming straight off of the Magneto and smooth, rectify, and regulate it for the LED inside. I've run these for six months of daily use and they are appear to me to be as healthy as when I installed them.

Next spring/summer, unless something better is on the market, an updated version of these from Philips that is 720 lumens, 7.5 watts, 3300K (slightly whiter which would be nice) and 25 degrees of spread to put more light down the road.

After much experimenting this is the conclusion I came to. The reflector is probably more important than the light itself. LED's make great flood lights but they're hard to project.

They look great in the garage but as soon as you start moving you realize you can't see 10 feet in front of you unless they're reflecting off something else. :)

Re: decent led headlamp diy for Puch

Stop torturing yourself!! Go down the rabbit hole with me to a secret world of linear electron travel a long step away from it's inherent wave nature.

And please follow this proven by the clutz of the century --me in this best way learned is always the hard way. All substitutions are on you.

1. Known 50- 60 watts electric coil that can be or better is FLOATED .

2. Two floated ends to five wire volt reg/ rectifier ONLY TRAILTECH do not substitute unless u know equivalence or better. The DC out ( one of the five wires isn't really moped critical ) and the output to quality led.

3. Headlight is definitely Larson lighting. I can't find a even vaguely quality build. But make sure you follow the polarity perfectly

4. #3 means no frame ground for anything but the ignition coil. So yea u better understand and get what's needed for a decent loom or if careful mod of existing wiring. A recent poster told me using a combo of existing 40 yo loom and new jumps for 12 v dc when maybe it was 6 v ac is gonna fry the coil. So far so good. Led wiring dc can be a bit smaller gauge esp to other than the 35 w DC headlight which is quite bright.

5. The original brake light is now led require NOT using power off backside of ignition coil unless u possess advanced degrees in theoretical physics, the brake switches need change to reverse and because lack of frame ground, yup more freaking wires near ur controls to be unable to hide.

But the light is fabulous. I couldn't get enough from halogens or mult hone made LEDs to survive though my Magnum has still a chinese led with a ballast grafted into a cev 6 v light with the oem guts removed and the led with it's own fan is mounted. That's the five wire trailtech and the general smoothnees of it's amazing build keeps it working whereas on my vespa s with more vibration from that motor is quite prone to poof I'm permanently dead quickly.

Re: decent led headlamp diy for Puch

The Larson one fits moped headlights picture perfect. Use a few of the oem clips and throw on some glue that holds but easily removed.

I looked at the Larson catalog the other day and they seem most promising. The reflector is engineered to house multiple LED's which is what you want. The price seems very reasonable as well. The non-DOT compliant one piqued my interest in particular.

Is everyone familiar with the MR16 "landscape" led lights?

These are not at all 1156 bulbs. I finally scrapped the idea of fitting them into the existing Puch lamp. I just mounted them in place of it on a small adjustable (for beam height) rail.

These are technological serendipity to the Puch. They have their OWN REFLECTOR. It's built in. YOU choose the beam angle depending on which one you buy. They are miniature floods/spots. Two pin. AC input only (they live for what's coming out of our unregulated e50). They just love the range of volts as well coming out of these engines stock. Even better, there is a HUGE range of color temperatures, beam angles, and lumen outputs that you can spec for any one part number.

The 530 lumen with 35degree beam @ 3000K color is damn near perfect for my Puch. My unmodified e50 has been running a pair of them all summer long without a hiccup. No modifications or intermediate circuitry whatsoever. Straight up wired to the lamps. And usually less than 10 dollars each.

Like I mentioned above, I plan to try a pair of 720 lumen, 3300K, 25 degree spread bulbs next spring.

And no one, I mean not a single oncoming vehicle, ever once flashed me with high beams in over six months of frequent night riding in town and country. Some people in forums get their panties all knotted up over light modifications and the thoughtlessness and danger of it all. If anyone flashed me I'd PROMPTLY make adjustments necessary. (edited)

That's probably because 700 lumen isn't very bright. A HID is over 2000.

The difference is the light source. A halogen or HID emits light from almost 360 degrees where LED's are flat and therefore it's about 180 degrees. It's much harder to culminate.

Re: decent led headlamp diy for Puch

Well I've got all on my mouth Tain bikes and road bikes over the years. I've got hid on my road bike for commuting. Geez it must be 10 years old. It traitted as i recall a tailtech motorcycle accossory light. But modded to a lithium ion battery. It's nice as we're the light and motion / nite rider version. But really led is so much easier and cheaper. I use two lumina 950 boost $68 each. And getting a third.

The Larsen led stuff is very stout if u wirenit correctly. Please refernto my earlier post.

But I don't doubt u canake a better mousetrap

The white-lab-coated engineers at Philips have taken care of all that for you in the reflector and lens design of each MR16.

A modern well engineered road light does have a more elliptical than round pattern when shone on a garage door (for instance). Keeps more light where it should be and out of oncoming eyes. But the old lens in an 82 puch moped isn't really much improved on a bare round reflector in that regard so the MR16 is a reasonable replacement. I just like these cause theyre straight drop in, low cost, and available off the shelf from any hardware store if you need one on the road.

No it's a good solution, I'm just saying they don't make them with the proper focal point for street use. You aren't going to get anyone flashing you the high beams using LED's with a single die emitter, they're just not bright enough. Using multiple dies on the emitter makes the source point is larger so you still end up with a more floody light.

The next gen shit is lasers for that reason.

That MR16 only reacts well to the varying voltage of a moped because it's made to dim on line voltage. Even still, it's power circuitry is not robust enough for a true lifetime of cycling endlessly.

Without a constant current coming from a dedicated driver, the increased "life" of the bulb is myth. Add in vibration and you life is halved.

Really, halogen bulbs last forever on varying current and are ideally suited for a stock ignition moped.

Re: decent led headlamp diy for Puch

Thanks brad for posting an alternative to the ideas that have already been discussed.

Never hurts to have more options and if you haven't tried it why knock it? You can do almost anything with lighting and have it be better than stock 6v garbage moped headlights.

if you pop it inside a reflector and its looking too bright, or the pattern should be adjusted up, you can always make a cutoff like modern projection beam lights have, out of a beer can or something, and pop it in there.

the part about this being self regulated is sweet. I used one of these halogen outdoor lighting bulbs years ago and it didn't like the vibrations and high voltage, died super fast but was bright for the week or so it lasted

Ok so this is the Larsen high /low iie two level led tractor light as powered by as I've said the only way I know how to make this stuff work ie floated 12 v coil ( hpi mini here but I get exactly the same with a kinetic floated light coil on my y grande. ) Fed on this bike Into a two wire trailtech to a silicon rectifier from what used to be RadioShack. Two wire dc respecting the POS /neg clearly labeled on the Larsen light.

It's nice looking light that has a pretty nice in adulterated soft field that is great for moderate speeds in the dark.

I have an equally bright led set up on my Puch using Chinese motorcycle led bulb with a built in fan painstakingly into a hollowed out cev bulb but why all the effort. The Larsen is a plug and play if you give it DC and know what's positive and what's neg. So yea it's a wiring project.

Re: decent led headlamp diy for Puch

Re: decent led headlamp diy for Puch

I've used track lighting bulbs, had one on my NS50 for a minute and the trac tomos clipper thing,

The halogen ones are crazy bright and crazier hot. scorched anything plastic nearby.

had that same set of plugs.

correct me if i'm wrong, but alotta home LED's are setup to run on an AC charge and internally rectify regulate from 110AC wall voltage down to the 3-10V that the LED runs on. But I thought most of the track light setups that's all external to the bulbs? But then again, why should it be if they normally run AC incandescent 12v track light bulbs. then it's just got a rectifier regulator in the track light bulb still.

that's a pretty neat consideration right there, very neat indeed.

am I wrong? or is it just kinda plug & play.

Re: decent led headlamp diy for Puch

So yes and no. The LEDs that u replace your incandescent 120 v bulbs rectify to 12 v. The old school track lighting such a lightoleer etc have a transformer that drops to 12 v but I believe that is also ac. But now if you go to the landscape garden section of ace or home Depot there have recently arrived what appears to be 12 v ac rectified to 12 DC LEDs with the two prongs that fit in all the above applications. But as to what they look like in a headlight I would say try and report back.

Yes if the above bulbs work and have a.decent path it could be good. The thingie with led lights other than the gigantic emmiters on work lights , I think an array is necessary to give great illumination.

Re: decent led headlamp diy for Puch

Just tried this with a $2 mr 16 12v ac/dc bulb on my pug 103 drilled small holes near the pins and tie wrapped it in place so i could reverse it to original bay fitting in the future if i wanted to. Soldered wire and male connectors and tapped into original loom and wow 5w eqv 50w warm very bright light bulb has own reflector and even at idle its bright. Simon uk

Appears to be the most ideal spec to try on my Newport.

https://www.bulbsdepot.com/457523.html

I'll mount a pair. Maybe even a DPDT on-off-on for single/dual choice. 4000k is whiter than my current 3000. 710 lumens is brighter than my 620. 25 degree spot will throw more of that brighter whiter light down the road than my 35 degree current one.

I wonder if I had such good luck running these for a year is that the relatively huge heat sink (for the form size) hanging out in the breeze ahead of a 30mph bike for most of its working life keeps it much cooler than it was even engineered for.

I will honestly try to post a few pics of the road this spring (edited)
