How to increase the brightness in two wheeler head light

I use hero honda bike my head light brightness is dim. Can I increase the brightness in two wheeler head light or any other way to increase the brightness?

1.

Is the lamp (1) a bright LED or (2) incandescent bulb?

If LED then could it be fatigued due to overmuch current going through it, or to being in service a long time regardless how much current it has been subjected to?

If incandescent or halogen, has a dark spot developed on the glass, reducing lumen output?

2.

Does it draw large current, requiring clean connections throughout the power loop? Are any connectors tarnished, rusty, etc.? Including where wires are gripped by crimp connectors, etc.?

3.

Is it powered from (1) a generator or (2) battery?

If a generator, could brushes be worn?

In my bike incandesent lamp only.its powered from a dynamo

You can try installing a bulb that draws more watts.
The dynamo needs to be powerful enough, of course.

You might want to examine/test whether the dynamo has worn brushes, an open winding, shorted winding, etc.

The new bulb must match the type of receptacle, and it must fit inside the compartment.

Speaking from experience many years ago, there isn't much you can do. The bulb and dynamo are matched at maximum revs and it will get dimmer if revs are lower. I found it particularly irritating because while waiting at road junctions the light was too dim to see, or be seen by others.

As the power is limited, the only solution, without extensive rewiring, would be to change to a more efficient light source (more light for the same power), possibly multiple white LEDs but you would also have to convert the dynamo voltage to DC and provide some current control circuitry to ensure the LEDs were run within their ratings. Depending on your country road laws you might also have to have the new light tested to ensure it complied with legislation. I did experiment with a rectifier and small lead-acid battery with some success but you need somewhere safe to mount it and the work is quite extensive.
