To be fair, it was a long time ago, and I'm sure they're better now,
but I was getting less light than a burnt match going uphills,
BTDT

and blowing bulbs going downhills.

Zener diodes.
Some of the better lights actually had them built in.

Nowadays the dynamos have appropriate protection I believe. at least
the hub ones.

The SON on the 'bent gets full brightness at about walking speed and
showed no sign of blowing anything at 60kmh. I only got that fast
once with a halogen in, the LEDs of course don't care at all.

The Shimano on the Brom hasn't had to do more than about 20kmh, it's a
shopping trolley and station bike, who needs speed?

I pondered battery lights for it, and was using cheap ones, but got
sick of faffing about with them when folding. As a wheel with hub
dynamo built in, and a light seti (although halogen not LED), was
a bit over A$120 landed, I went for it. Still much more expensive
than AA/AAA battery lights, but in the realm of similarly bright
rechargeable packs.
