Just got my 21 silverado 3500 HD headlight bulbs swapped to LEDs, I replaced the weak OEMs with both Hi and Low AUXITO bulbs, and the difference was quite dramatic! These bulbs are much brighter...with a neutral white rather than the obnoxious blue-white bulbs from other makers, and they reach out farther with better clarity, so I can drive at night with better peace of mind and confidence knowing that I can spot something on or near the road in time to either brake, stop or avoid a collision.
As you can see, these LED bulbs are quite bright. Even in a well-lit area with streetlights and all sorts of other lights, the headlights outshine the other lights. Before this, the headlights would have blended in with the surrounding lights. On a dark road, on a highway, or in the rain, it would be extremely difficult to see what's in front of you without using the high beams (which I don't do because it blinds others).
