Headlight Bulb

Mine headlight has a 6V /25+25W bulb

I am thinking to give a try and change this with a led one .

But i must know what kind is the bulb connector.

I found one at Amazon with description Stanley A3625A 6V 25/25W T19L Clear Auto Bulb

The T19L is the connector i am looking for? As i find also the same bulb with P15D but this is for 12V i think.

As i read the T50, T80, and T80D have a bulb with code number 206-84114-60 and T80ED a different code number 02-84314-00, maybe this code is for 12V bikes.


Do you know anything about it?

LED bulbs wont work on a direct AC system as fitted to Townmate, they need to be supplied with DC from a battery. Also most of the LED bulbs for sale are for 12 volt. So looks like you need to stick with standard bulb, also whilst posting, dont fit a quartz bulb, although these are available in same fitting as standard Townmate bulb they again do not like variable AC voltage. I tried a few of these a year or so back but they only lasted a short time before they blew, the light pattern was poor and the intensity no better than standard tungsten bulb.

John good morning and thank you for the answer.

About three years ago I switched all the lamps on the motorcycle with leds.
I changed them to work at 6 volts.
I  left only the bulb in the front light.
I did this by using led to lower the consumption and have better lighting in front.
Eventually it was not worth the trouble.
The following photo shows what I built.

For the front light(finally it does not work properly) :



The back:



And the front winkers



I did the same for the instrument panel lights and everything works fine .

Now I'm thinking of modifying the lighting coil.
The electric diagram shows to be composed of two coils, one for charging the battery and one for the lights that is not powered by the battery.
At an old and damaged coil that I have to remove the old wire and instead of two coils to wrap one with more spirals.
This will increase the output voltage. My purpose is to produce the maximum possible voltage from the coil.
The CBF600SA8  that I have the voltage from the coils that feeds the regulator is about 60 volts at 5000 rpm
Maybe I'm building a regulator or maybe I buy a used genuine one that works at 12 volts.
All this because I think to put a better lamp for example an H4 or even a xenon projector for small bikes at the front light.

What is your opinion on all this?
Do you have anything to suggest  ?

If I fail then I will finally stop working on this conversion

A lot of work and only worth it if you are doing a lot of night time rides. Frankly I rarely use my bike at night and then mainly on urban roads with good street lighting, so its not a mod that I would undertake.
Your LED indicator is worth doing though as the indicators do not show up well in day light.

Indeed, the leds do not look good at day light, but not the ones that are made by us.
The leds that are on the market are not profitable in my opinion.

I have also used high bright leds with a 60 degree radiation angle.

Anyway, I will continue trying to achieve the performance I want.
If the conversion to 12V will be not only a voltage increase but also a power increase , then I will initially use a 12 volt and 25 + 25 watts lamp, and then 35 + 35 watts.
If I still do not satisfy with the result I will continue to another type of bulb or even change the mirror internally the front light.


Thank you for your answers again.

hi Duckrider

I am most impressed with your trials with LED lighting, BUT is it worth the effort ? I find the application of LED'd for lighting to be not particulary effective unless special reflector systems are employed. Like JW I rarely ride at night so concentrating on the indicator problem seems where the energy should be put.
Having bikes with ancient Villiers flywheel generators (AC) I have had good results using halogen type replacement bulbs but admit to not doing a lot of night riding.
I think , if I were inclined to get involved I would attempt to look at a 12V solution but I wonder is it worth the effort in practice?
cheers

Hi Steve,


First, i am 57 years old and i have plenty of time , so i have time to work with the motorbike as that is a hobby for me


The leds I have used are the simple 5 mm diam.
For winkers, I built a 6-volt flasher unit that does not controled by the load. I have to do this as i can't find a 6 volts one for sale.
Also, each light has its own voltage regulator using a LM317 set to operate at 3 volts. In this way, the white leds operate at the maximum voltage without any change in voltage causing a change in brightness even if the battery voltage falls under the 5 volts.
You can see the back light at the next photo:





As you can see at the photos i did not cut and did not modify the existing wiring, I made a plug from an old lamp so the rear light is working but the whole construction can always be rewound to the original condition.

I know that with the use of a suitable special reflector , the led produce the correct illumination ,brightness and shape.
But here I can not do anything about the front light. Maybe i will keep the front glass and change the inside reflector.
The construction at the moment is like of those who place xenon type lamps on old lights without proper specifications, which has the effect of disturbing the vehicles in the opposite direction.

If I ever manage to build conversion to 12 volts I may be testing and a lamp like this.

All these remain just dreams at this moment.

hi duckrider

I admire your patience and even though I worked in Electrical Engineering for over 50 years I never got the urge to play with electronics and much prefer a spanner or lathe these days.
Your work looks very neat and good luck.

Cheers

Looking great so far. Keep us posted. Good luck.
