This is an interesting question about halogen vs led headlights in snow.

At the first, I think halogen and led headlights are all good.

Halogen shall be litter bit stronger penetrating than led headlights in snow.

Because most of halogen headlights are 3200k with warm white.

But led headlights shall be 6000k with white lighting.

In order to make you clearly our halogen vs led headlights in snow, I will show you pictures as below.

If you have any different idea about halogen vs led headlights in snow, please inform me without any delay.
