Maybe it is made from gold. Very Happy

It's better to make one yourself.

My Tmate is 6V and in the future I'm thinking of turning it into 12volt.

Here is the electrical design of the diy regulator:

Not sure that the standard T80 generator can put out 12 volt, see this thread http://yamahatownmatet80.forumotion.co.uk/t664-6-volt-to-12-volt-conversion?highlight=12volt+conversion so a new regulator wont be much use on its own

Looking closely at the electrical chart, you will see that there are three coils, one for the ignition, one for charging the battery and one for the lights not controlled by the battery, and this is the reason why the brightness is related to the engine speed .

Of course a 12-volt regulator needs a 12 volt coil.
But the best solution for someone who wants to experiment is to remove the two lighting windings and wrap one with larger diameter wire and more spirals.

In this way it is possible to increase the power, which is required since the existing lamp is 18 + 18 watts and the lower halogen is 35 watts.

I personally believe that it is useless to use the existing prehistoric value and age bulb Very Happy

Crazy price, I have several of these for sale with mounting bracket @ £13 each including p&p

But of course it's expensive, 'cause ours Townmates are pricelles... Shocked

The correct headlamp bulb for a Townmate is 6volt 25/25watt no wonder your lights are dim.

This is right, the solution to the problem is another 12 Volt  light/charging coil but with more power for an H4 halogen lamp to work.

Is it all these, products that we can trust?
