I mounted a Problem Solvers braze on mount and a handlebar accessory mount to my front fork and it works great. I have a handlebar bag, and little room on the handlebars, and recommend this set up. Also, I mounted an old cell phone as a cheap bike camera (one too many close calls with cars).

Or this :

My fork has no eyelet to screw a bolt into. So I made this mount. In fact, I made it on two of my bikes. I made one out of copper pipe and the other out of PVC pipe.

Here is the album with all of the pictures.

There are definite advantages to having threaded bosses on your fork blades!

When I needed to ride recumbents, I struggled to find a good place to mount a dynamo headlight. It appeared that a fork mounted light would be best, but I needed to create a mounting point.
My solution was to get a T-shaped bracket at the hardware store and attach the left and right side of the "T" to the fork blade with hose clamps, and use the bottom of the "T" to mount the light.
I wrapped old inner tube around the fork blade to protect it.
Here's the result...



It's not pretty, but it did work!

That's really nice work. Sometimes you have to give up pretty for practical.

I think a fork crown height is best for lights.

I bought a used dynohub wheel for $20, I had a vintage dyno powered headlight in storage, I put the wheel and light on my errand bike. But the light is too low, any road debris (leaves, etc.) create large shadows. Since it is on my errand bike and is only used on well light city streets, it is good enough. So, not going to change it. Light is mounted to the fender mount on the fork with a piece of threaded rod.




But the plus side is that it was the simplest wiring job I have ever done. Both hub and light are grounded to the fork, so only needed one conductor wire.

I've read plenty of comments about the ideal height for the placement of a headlight. Mounted at the height of the axle of a 26" or 27" wheel has problems. I haven't had the shadow problem, but I find it's harder to aim properly, since aiming it too high is bad.

The fork crown is a good height, but to me, so is the handlebar. I also find that I am not annoyed by people wearing helmet lights, and I haven't had those shine painfully in my eyes. The painful lights tend to be on handlebars, but the problem is the light and the usage, not the placement.

I suspect most people with lights on their helmets are using headlamps designed to go on their head for camping. And those usually have a pretty wide beam so that you can see a large area close up. Some of those headlamps are quite bright for runners that run at night, such as ultra marathoners and need the brightness for jogging or running speeds, but they still would be using a wider beam than a typical bike light.

And the most common headlamps are very light weight, lighter than even light weight bike lights, thus not a lot of battery capacity.
