Dynamo light for dutch bike
 

I need a new Dynamo front light for my dutch bike.

What light do you recommend?

I believe I have a supernova E3 Pro 2. (I may be wrong... it was years ago that I bought it.) It comes as a set with the rear light. It's... good for a dynamo light. It has a slightly wider beam pattern than other dynamo lights I've seen and that makes it a bit dimmer than them as well. I've only ever used one dynamo light, so I don't have a ton of experience.

Peterwhite has a good page on dynamo headlights, however I'm not sure how often it's updated.

What kind of dynamo; and are you replacing both the dynamo and the light, or just the light?

This is important; because you are posting in vintage, you may not have a generator/dynamo that will work with most modern lights. The generator, as well as identifying information of the lights you have now, would be useful.

I have a shimano dynamo hub. I'm replacing the light and the cable.

I think the light I had was something like the Busch & Müller light now.

If you have a relatively modern Shimano dynamo hub, it should be specified for the "standard" 3 watts. If so, then you can use any B&M dynamo light. You can order them cheap from bike-discount.de.

However, B&M lights are usually quite dependable. So, unless you damaged the light or submerged it, I'm wondering if the light itself isn't the problem? Maybe it's a loose or frayed wire somewhere?

No I removed the handlebar and the broke the wire and I'm going to upgrade to a better light cause the light don't have on and off button.

Too bad about the breakage. Replacing the wire would solve that, but not the switch issue.

Most dynamo lights do not have an on/off button per se, though many do have a swtich on the back of the light.

The B&M Cyo series has a switch on the back of the light. I like the Cyo Premium; it's the brightest Cyo.
The B&M Luxos U has a cable that goes to your handlebar, with an on/off switch and a USB charging output. Nice! But expensive.

I have three B&M lights, different versions of the Lumotec IQ CYO series bought at different times. All are wonderful. One is powered by a Shutter Precision SV8 dynamo hub, one by an old (~35 years) Cibie bottle generator on our tandem, and one by an even older (~45 years) Union bottle generator. The generators have different behaviors but the lights are awesome. All are paired to a B&M Topline taillight.

The SV8 is spec'ed for road bikes or smaller wheels, not large-wheel touring bikes because it needs to be run at a minimum speed. At walking speed the headlight flashes with every magnet pulse. Once I'm riding however the light comes on and stays on even when I slow down. It is my prime night commuter bike.

The Cibie is a low drag, lower power unit that needs maybe 10 to 15 feet of road speed to charge up the light. At walking speed it doesn't drive the light at all for even further. One we get going however it drives the headlight and taillight just fine.

The Union is a German-spec full-power-at-low-speed unit that fires up the headlight immediately. I can flick it with my finger and the taillight comes on. Of course it also has more drag at intermediate or higher speeds. It has absolutely no trouble driving the lights at speed. It lives on my fendered bike.

The dynamo light I used above has an on/off button. I've never turned it off. I don't understand why you would want to.

Before DST kicked back out much of my commute home was well after dark. Several miles are on the Minuteman Bikeway which sees a LOT of commuter traffic. Unfortunately many of the other cyclists and most of the walkers and joggers carry weak lights or none at all. A bright headlight aimed forward enough to give advance warning of debris on the path can be blinding to oncoming cyclists. (Walkers can always stop for a few seconds and wait for a bike to pass.) I usually run with two headlights, the generator-powered B&M and a USB rechargeable. The B&M is mounted so that I can't easily change its angle but I can re-aim the battery light. So when I approach another cyclist I turn off the B&M and angle the battery light downward and/or cover it with my hand. It's just courtesy and safety.

I ride that bike mostly on bike trails and there is no need for having a light during the day.
These trails are away from road traffic so I don't need to have a light going on disturbing other cyclists.

Cheap as I am, I'd probably just install a switch on it when I was repairing the wire.

I just switched mine to a B&M IQ-X. Couldn't be happier.

I'm thinking about going with this one:
