Bright Headlight for Winter - Recommendations?

[portals]

Weather has been very good for time of year, been out on bike way more than I thought in dark, the headlight I have is rubbish and so dangerous so been looking past couple of days for a more powerful front lamp.

Mostly they seem to be LED arrays and make all sorts of claims about how bright they are and how long battery will last, mostly derided in the reviews and batteries dying in months also seems common.

So looking for recommendations, not looking to land planes but need something that will actually show me the road ahead so I can be safe a go a little faster than 10mph...

Thanks.

I should've said majority are all 5V, I have USB on bike but also have 52V, most seem to recommend just going USB power, has anyone here tried 36/48/52V headlights?

There are very many good lights on Ebay, Amazon, Aliexpress, etc for around a tenner. Many have their own separate 4-cell battery pack. You can get your own empty 4-cell holder and put your own cells in it, then you don't have to worry about the quality of the cells.

Two of these 12V-80V lights are soldered to my ebike battery:

...this larger version too - had to solder this on in series with one of the two linked above, because it can't 36V:

Three, because the spread of one light beam of one or two, wasn't wide enough to clearly illuminate potholes, and as my speed increased I didn't want to be adjusting the angle to throw light further ahead. The third (largest) one is at the apex of the light triangle, casts furthest out with a slightly wider beam than the others. Wish these lights had adjustable lenses so beam width can be altered. An eye tracking system to focus lights on whatever I look at would be nice. They haven't blown the inline 2A miniblade fuse, must be using less, I haven't got around to measuring, should have before I soldered them on. At some point I will get around to using two or three fuses in series, because about 14m 5s in this video, this Grin dude says quick blow blade fuses can fail to blow quickly enough:

Have decided to just go with USB 5V and not bother using 52V for an easy life.

Looking at this one, only concern is the batteries seem cheap and don't keep charge.

So here's a question, not clear from the blurb, can these lights be charged with 5V USB when you are using them or like a lot of devices you cannot use them when charging, does anyone know?

I have USB on bike so if/when battery fails I can still use it without hassle of replacing cells etc.

You can connect an older car headlight to a 12v battery.

This or something like, or three:

...with this, waterproofed somehow? Or perhaps someone can post a link of a waterprofed product which does the same? Seems these can be stacked to make larger battery packs. Although... on a bike constantly being moved about, and with springs possibly becoming hot, I don't know how long they'd last.

... with a rainproof two wire switch:

...and a 2A fuse (or two) inline?

When the cells are destroyed, easily replace.

Easier to solder lights to the battery.
