Only leds on that site are for trailer tow. Lots of halogens tho.

Just google "1156 led bulb" and find the voltage and polarity you need. AC/DC types are available, and a lot of sites sell them. All I could find were equivalent 15 cp or more, so may not be good for park/cowl or interior.

I purchased the ones from classic dynamo & regulator conversions. Part no BA15d. So far so good. Just plug in and drive after normal headlight adjustment.

For some of the other bulbs, 1156,1073,1144,67 converts to LED BA15S.
1157 is BAY15D. Have not been able to convert all other applications ie. #89 Tail Light Lower, #97 Dash and Interior light. If others are able to find direct LED replacements for other numbers and applications please let me know so that I can include in my bulbs cross reference list. My email is jrelliott42@gmail.com

All original bulbs except headlights are ba15s base. Headlight is ba15d. For added turn signals, bay15d (21/3 cp) in cowl conversion and ba9s for the pilot. ba- is straight across pins, bay- is offset. 7/9/15 is diameter (mm), s/d = single/double filament.

I read somewhere to convert candela to lumens, multiply by 12.5, assuming at least 120 degree dispersion of the led.

Not to hijack this thread, but I purchased LED replacement bulbs for the stop portion of my tail lights from Berts. I replaced the right bulb and checked the brightness against the left stock bulb. I didn't see any difference.

If you were to replace all the bulbs with LED bulbs, then your total current draw would be less than 5amps. The only real problem would be the turn signals if using the original sockets for tail and front as would not be enough draw to make the thermal flashers work.
I personally like the idea of reduced current draw. It is just a matter of finding a relatively inexpensive source for all the bulbs as the headlights are still a little costly for the 50/32 cp replacement

Just curious here if putting LED bulbs on the headlights can blind oncoming traffic.

I found these. I am thinking about buying a few to test out and they are quite a bit less expensive than the dyna more bulbs suggested above.

I have thought about those also Dave 1929. I'm not sure if they would focus well for night driving but may work well for daytime so people see you better. I tried calling them to get info but just got a recording. I left a message and they never called back.

Looks like a parking bulb on a headlight base.

Puts out light in all directions and is low power. Good for a warning light.

Dave,
Those bulbs will not work as headlights. The forward looking LEDs are not focused. The side LEDs may focus some. They can be used as brake/turn signal lights.

I used some very like those in a model T. It was actually an improvement over standard. But it's not for everyone.


There is not many LED offerings in 6 volt that aren't from specialist suppliers, which are hard to find (And harder to find in positive earth! But i see that dynamo specialist place linked above has them). One option might be to modify this 6 volt lamp.. One option might be to modify this 6 volt lamp. https://www.aliexpress.com/item/COB-...820759057.html
But the effort required, particularly to the cooling might make it easier to simply pay the big cost & shipping from one of those UK places that has some ready made.

Also see they have one much like the UK place offers but from china, and for similar money, positive earth but only 900 lumens? https://www.aliexpress.com/item/Zaul...719482964.html
The British probably offer a better warranty though.

What would happen if you put some tape over the forward looking LEDs and used the side ones to focus.

For 12V, there is a flasher that works both with LEDs or regular bulbs, or a combination of both, Novita EP34. Autozone had them for around $10. They do not depend on current draw, but rather must work on a timing sensor of some kind. The EP34 works with 6 bulbs, the EP35 works with 4. I recommend the 34 as you need to count any bulbs you have on the dash that indicate flashing.

I've used them for headlights and the forward facing LEDS are about as bright as a tail light. They won't do any real harm.

The LED replacement I'd really like to find would be for the dash light. I really want a solution that doesn't make the casting scorching hot when I try and turn it off. I've achieved good brightness with the 50/32 bulbs from Bert's by polishing the reflectors inside.

LED replacements are designed for maximum retina scorching. Not likely to find much below 200 lumens, which is too bright for your eyes to recover fast enough to keep between the fenceposts. Best stick with the 3CP #63 bulb, which is maybe 30-40 lumens.

old31. Yes you did the math correctly- I think it was 82.00 total to get it to the States.

I like them thou. Is it worth 82 bucks? who knows. They are brighter and give a nice white light, .
Just need to get the lights aimed correctly.

Looking at the construction of those bulbs, I wonder what the focus pattern looks like. -?

I saw one at Hershey, the focus pattern is sort of a figure 8 and fuzzy
The original bulbs have a V shaped filament, gives a sharp focused beam with clear edges without the lens at 20 feet just a little larger than the diameter of the light, the halogen bulbs I have use straight filaments, the focus is a little larger and some fuzzy edges--- so 1/32 makes a difference, the led bulbs move the light 1/8", and only 2 spots of light-- I think s lens could be designed to work with them, when led bulbs are OE the reflector is much different, sort of a cut in 1/2 rams horn

The real test is not how brilliant they look looking close, but how far the concentrated light is projected down the road---- most electric poles have reflectors, my car lights them up 8 poles away, about 1/3 mile--- 35 watt halogens, everything else original, including generator, never charged except by driving, I am going to try some hid bulbs, but for low beam it will have to tilt the bulb

I got it from Super Bright LED's. I'm pretty sure it was this one. https://www.superbrightleds.com/more...ofit-car/2077/ Check the base size because I bought it over three years ago. I'm not near my car or I would check.

The dash light? i forget what size that is but it doesn't look large.
Maybe adapt one of these?
https://www.aliexpress.com/6V-LED-Bulbs-P5W


Or solder this in an old broken bulb
https://www.aliexpress.com/-LED-Conversion-upgrade-Dashboard-bulb-5v-24V

Rated from 5 volt up to 24 in the same bulb huh?


Then this one looks like a straight swap for a headlight bulb, and doesn't need to be modified for focus.
https://www.aliexpress.com-6-1200LM


Seems to be a few options out there.

That one might do if soldered into a BA15S base, but voltage spec at 9-14V.
The only 6V BA15S offered by superbright these days is forward firing.
Maybe a 12V (AC/DC) @ 250 lumens or so would work. LEDs are usually dimmable.

That one appears identical to the one from GB, down to the same number printed on it, except different size print. Half the price, guaranteed, but probably not pre-tested.

I'm still skeptical about the focus; Henry's reflectors just weren't designed for them.

OK, the LED I used from Superbright fit the stock dash light with no modifications. So I guess I'm mistaken.

Badpuppy, do you know what base fits the stock dash light? I have a list of LEDs I bought but I am not sure which one I used. I thought it was the one I linked to above...

John,
There is a company in England, they need to know some particulars and when I last checked, 3 bulbs, two for installation, and one spare was around $128.00. There are some other threads on this subject, lots of good info. Also, these LED's as I understand it are very bright and will do great. But, they cannot do well with poor reflectors, The silver on your reflectors has to be up to snuff too! I do not recommend what I did, I replaced the reflectors with a sealed beam kit that hides behind the Model A lens and looks OEM, but, the current draw is high and if you have an original Model A Generator, you have to up the charge to around 15 amps if you do a lot of night driving, and if you up it and drive during the day a lot, you are boiling your battery with overcharge. I bit the bullet and installed a 6v pos ground alternator! But starting on this again, I would have done the LED's got my reflectors re silvered and been done with it with real bright lights!

Default Re: led light bulbs

The headlight specs on the aliexpress site show 930 lumens, roughly equivalent to 50+32 CP. Difference is that both LEDs light on high beam, so it's more like 80/40 CP. Obviously it throws a lot of light out there. However due to the thickness of the mounting, there's a significant dead band between the two LEDs, explaining the figure-8 pattern. I'm sure they will do for most folks, but Henry's rolling.
