Be very careful when trying to “improve” the head light.
If you are replacing a bulb or a headlight you are messing with the original DOT submission. The stock Bosch headlight assembly has reflectors built in to direct the light down and to one side (in US, to the right side) to prevent you from blinding on-coming traffic. What many of you don't take into consideration when you start trying to make your light ultra bright, and white, is that you are most likely going to blind on-coming traffic which is probably the most dangerous thing you can do with a headlight. There are very specific requirements when placing a headlight on a motor vehicle, it's to protect you and the other road users. Just as you don't like it when someone drives with their hi-beam on all the time, that's exactly the douche move you end up doing.
If you plan to do some sort of a swap, at the very least look up the DOT requirements of how far the light can cast, at what height, and to which side it must dip in your country. Then notice that your factory lighting had to meet that criteria and consider that you might make it brighter, but to make it cast farther the compromise is to create a dangerous situation for the cars that are now driving directly towards you in the dark while being blinded by your headlight.
The reason you think stock headlight sucks is, that Ducati use inadequately thin wire for headlight circuit. (18 gauge)
The stock Bosh headlight (reflector and the lens cut) is actually pretty decent, IF you use relay, heavy duty wiring harness, and quality H4 bulb.
Years ago, I wrote about this.
http://www.ducatimonsterforum.org/index.php?topic=69572.0The best 7” round headlight I have tried is CIBIE 82440.
I have them in my DD (NA6), with 10 gauge wire custom harness, relay and Wagner BP1210 80/100w.
Before CIBIE, I had Hella E-code.
The difference?
The CIBIE put a lot more light out to the sides on low beam. I see so much better through the corners.
The high beam is also better (CIBIE lens has better cut-off), putting less light up into the trees, and more importantly, into the reflective road signs.
Yes, the reflection from those signs are dangerously dazzling, so your super bright head light may be less useful than it should be, IF the lens doesn’t have proper cut-off.
On the Monster, I still keep the stock BOSCH, mostly because, well, because it is slightly bigger than 7-inch, so I would need something like this if I want to run CIBIE.
https://motowheels.com/i-7935658-corse-dynamics-7-inch-headlight-with-adapter-ring.htmlStock Bosch headlight, with heavy duty harness + relay, and slightly high wattage bulb, AND a pair of Cyclops Long Range Optimus ramp, that’s the set up I have on my bike (now).
Both set up are for riding / driving through tight, twisty backroad in the night time.
If you are only riding in the city / freeway, the set up you’d need may be a little bit different.
