You will see a reduction in use-able road beam pattern! Bright appearing, but in the wrong directions. You will also have headlamps that put out almost no photons in the orange and red wavelengths vs. incandescent that put out a lot in those bands. So who sees red and orange signs and road cones/ construction stuff better??? If you like brightly lit trees, underpasses, and plenty of dangerous off-axis glare in the face of oncoming traffic go for it!

Also be prepared to lose the higher (above horizon 'bright' position) / lower (below horizon traffic driving) beam pattern shift. None of the available LED headlights correctly form or shift beam patterns.

Amperage load? Yep, those A's with generators that ran all over the place day and night for many many years are suddenly all in peril now that alternators and LED's are available.
