Upgrading an on/off bike's headlight...

Hi mates!

I write to you today so as to have some more opinions about what I'm willing to do in a short time...

The bike headlight looks like this from stock.. (That's an actual picture of my bike)



The stock bulb is a H4 35/35w, I swapped it for a 55/60w ("xenon effect") and it certainly improves, but isn't enough for night riding...

About night riding.. I know it is better to ride with daylight and all.. but as many of you may have experienced.. There is always something that delays you and sometimes you have to do part of the planned ride at night...

The most of my riding is on road so my worry is about having good light to see on the routes and also to be seen...
With the stock headlight and the 55/60w bulb I get seen by other people, but I don't see much... (and also have been in some trouble that scared me a little because of that)



So well, enough talking about the bike, now.. the plan of upgrading the headlight would be something like this.. (The headlight cowl will be gone, and I'll see if I make some kind of mask or just leave the round headlight naked). The plan is to put a bixenon projector in the big round headlight and a H3 35w aux light would be the small one in the right. And also putting a low fender so as to get the most of the light output.



A link to the projector sale..

About just putting a bixenon kit in the stock headlight, I think would be brighter but it wouldn't open in a good big pattern just because the headlight's size.

Well that's the actual idea...
Hope to have some inputs about it and tell me if I'm wrong with something or I could do better with another option or something.

The idea is to have this projector and to keep it if I have to sell the bike and possibly use it in another one and so... Not to mod anything from the stock cowl or fender, so as to store them till I have to sell the bike.

Thanks for reading!
And thanks in advance for the answers.

You could do something like this:



The backside;



That's two ADVmonster 60's. 3600 lumens each, 56w total. With the rotary dimmer it doesn't seem to bother anyone on the road & the night vision is excellent. Trail riding people see me WAY before they see the bike.

Power limitations

Keep in mind how much power your bike puts out.

You can easily over load the stator and burn it out.

Just sayin'.... and don't ask me how I know!

Almost all motorcycles use a shunt style regulator, the stators run WFO all the time with the regulator shorting out the excess to maintain ~14 volts.
Your logic is flawed, Just saying

You can easily fry a stator by drawing too many amps. Just saying.

P = V I

A permanent magnet alternator is running WFO all the time. If there is no demand a shunt type regulator grounds the output, a direct short of the output. You are not going to hurt it with too big of a bulb.

An alternator with load coils instead of permanent magnets like on a car is a different story.

Applying current loads that exceed the rated output of ANY alternator WILL cause the windings to heat up excessively and WILL eventually damage the alternator. How fast that happens depends on how much the current demand overage is, how well the alternator is cooled, and how often the overage is applied.

For illustration; 20 amp (rated) alternator will not be happy when it's being asked to supply 30 amps.

Then there's the associated risk of overloading the rated capacity of the wiring.

Any electrical changes must fall within the rated parameters of the entire system, or a fella is going to get himself one or more of: constantly blown fuses, a damaged part, stranded after dark without a working headlight, or an electrical fire.

A bit heavy but you will see everything! Dual 4" HID, 35w each (one euro beam and one spot beam)
