Has anyone seen or heard of L.E.D. headlights for the Model T? They now have them on many new cars, especially European sports cars.
With the development of solid state inverters and micro-power packs, it seems like the industry is getting nearer to something functional that might work with Model T's.
Anyone have any ideas??
I have LED headlights on my 11 touring, powered by a motorcycle battery underneath the rear seat. They draw ninety eight milliamps each so the battery will last for hours if needed.
Do you have a brand name and part number for the motorcycle headlights you used? Do they fit inside the various year's Model T headlight fixtures?
Information and/or pictures on how you mounted them in the Model T gas headlight would be appreciated. I want to install them in my '14 speedster with fogged glass to "hide" my modern day cheating in place of the the gas headlight components with clear glass lens that shows all.
Thanks for your help.
Out of curiosity, what is your desired outcome ... brighter lights ? Less
power draw ? Something else ?
LED lights are highly directional. That is the reason replacement tail light globes have rings of LEDS around the bulb as well as those pointing rearwards. This is done because such lights have no reflector. Arranging multiple LEDS to make a parabolic reflector do its job may not be entirely possible. LED forward projecting lights have their own individual reflectors for each LED, grouped in circles like traditional lights, or in light bars.

I cant out run the lights on the roadster! With new reflectors made a big difference. Now I can see 30 feet instead of 10. I installed battery LED bicycle lights on the rear that clip on. They run 72 hrs on 1 AAA battery.
I have them on my 1915 and 1919. I have my lights wired up to a battery and the LED bulbs draw next to nothing. I don't remember the name right now, but I got them on line. They were about $10- $15 each. The "warm" bulbs look more like the original incandescent bulbs. The "cool" bulbs look too bright white.
Note if a combination headlight/horn is used, you CANNOT use it to run battery headlights and magneto horn. You will need to add a different light switch or replace the magneto horn with a battery horn.
Since my cars have no generator to charge the battery, I can run my lights for hours and not worry about getting caught in the dark.

Here's a few motorcycle LED sites to search. Looking at the site line-ups, they appear to be for 7" motorcycle headlights only.
Hoping to get high headlight output with low power consumption while maintaining original Model T appearance.
Jim, maintaining the original appearance will be a problem. Most motorcycle lights are 7". Led specific lights will have multiple small reflectors and will not look at all like standard T lights. HID and LED lights need their own special construction to make the most of their lighting qualities.
From my search of a number of web sites, you may find LED replacement globes for T headlights, they will draw less current, but they will not give an efficient light spread with a T reflector.
Good LED lights and light bars are made the way they are for good reason.

Might want to take a look at LEDLight.com on the internet. They are located in Chandler, Arizona. They have 6 volt, negative ground bulbs with 1156 and 1157 bases. They state that they will work on all 1909 thru 1927 Model Tís. They run about 5 or 6 bucks apiece, plus shipping. I have some and am in the process of converting, but havenít completed the process yet.
If led would work in a mag only car I would like to learn more.
I am using these:
They work for head lights or tail lights. The headlights work great on High Beam and act a running lights on low beam. I buy the Cool White. The headlights work perfectly with a clean reflector and display a perfect beam with no black spots.
I suspect they would even work off of the magneto as the voltage rating is from 10v to 30v.
LEDs require polarity correct DC current. You will need to use a diode? It would be like the hot shot setup if I remember right.
These LED's work on a 12vdc system.
They should also work on the Magneto as one half of the cycle would be the correct polarity. If you wanted to get more voltage from the magneto, you could wire in a full wave bridge rectifier.

If you are on an original 6v system, you can use a 6v to 12v step up converter to drive the headlights, listed here:
Looking at the site, I am curious if you know the 'lumens' those bulbs provide? Just being prudent and cautious. Thanks.
The web site says 270 lumens, but I was quite surprised after installing them in both my tail lights and headlights. They are actually brighter that the 12v conventional headlight bulbs I purchased from Langs. The key is to clean your reflectors. These LED's put off a 360 degree light and reflect perfectly with no dead spots as you get with incandescent bulbs.
If you purchase the two element type, you will need to run the headlights on high beam at night. The low setting works great for running lights.

LED Low Beam:
Found a FAQ column about 'lumens vs candlepower'...
Rod, I understand about the reflectors and a necessary focus for our T's, but how well do your lights reach out to those 'deer in the headlights' situations? Thanks.
I use the same bulbs and setup as Rod. They work just fine, and are adequate for even totally dark roads.
These other bulbs are rated 6-24 volts AC or DC. They'd probably work off the magneto, though I think a better setup for mag-driven headlights would be a sealed lead-acid battery with John Regan's magneto charging circuit.
Please re-educate me about mounting/latching pins on the bulbs...
1156/1157 pins are staggered. Are the pins in our model T sockets staggered or straight across from each other?
I can't manage to get the rims off of my head lights right now to check and cannot find my spare light socket.
One image I found shows the 1142 with staggered pins also.
Would you fellas expound?
I'm quite excited to "perhaps" to be able use LED bulbs with a magneto system on my 18.
Duey, the pins are not staggered as far as I know. If the wrong fillament in a light shows, it can be corrected by removing the light socket and inserting it 180 degrees around.
Can the same be done with the LEDs in use?
Allan from down under.
After my recent exciting adventure with the so-called "magneto bulbs", I believe I'll try the 6-24 v LED's and see if they light any better than the 1142's I'm using now.
Allan is correct. 1142 pins are not staggered.
All interesting information. Looking forward to hearing how they may work in a magneto only car.
