Yep, by default CBF500 uses a standard H4 dual filament bulb (for high and low beam). Dunno if you could easily swap that out for anything better without replacing the whole head light unit.
Prob easier supplementing it with other lights as others mention. ____________________ Beginner Biker Adventures Blog

Swapping the headlight unit is the best option, did not say it was the cheapest. It is also very easy.
Beam is optics and has nothing to do with position. This is why the reflector design and size are so important. Tiny shitty spot lights are going to give you a tiny shitty spot and a far too intense beam for oncoming traffic. Consider a normal bulb has the end blacked out, the entire beam is from reflected light, off a 4" reflector. A spot light has a tiny 5x5mm led and is focused, rather than spread.

If you look at modern cars you will notice that spots and additional running lights are generally incorporated into the bumper or lower valance. This is for the reasons I have already stated. |
Then headlamps would also be mounted down there. If I look at modern cars I see style over function, a common example of this is rear indicator lamps mounted inside the brake lamp, often in a x pattern, confusing and hiding the indicator signal. Please explain this.
Headlights are for seeing, day running lights are for being seen. Fog lamps are put low for the purpose of getting under the fog and allowing maximum visibility. Day running lights are put there and everywhere else for cosmetic and style reasons only, they add nothing for the driver, and they dont need to, the headlamps are quite good without them. |

Yes it does. Headlights are designed to work within a defined height so as to give a correct beam length without dazzling oncoming vehicles.

And this is why they should be mounted low and at an angle below 90degrees to the vertical. The focused spot then becomes a long ellipse.

I agree they are crap but have no relevance to front lights.

Auxillary driving lights are not fog lamps or DRL's so your arguments make no sense.
Auxillary lights are used in conjunction with the headlights not to replace them and are used to supply light everywhere and as far forward as possible (remember that long ellipse bit earlier?).
The problem with creating a highly lit spot is the driver concentrates on that spot and not the surrounding areas, a sort of target fixation which is why ideally you have a long ellipse of light. |
