yeah LED's are not that great, or most I have, for tracking blood at all
but enough lum's and things do be bright no matter the color of them
you also get into if there spot or flood lights too, in them
one is a more tight beam and other is a wider spread of light!

like all lights, they have many versions,
but you can still find cheap powerful lights for an atv these days , pretty easy
and not use as much power as the non led OEM light;s do!
