LED Headlights installed..

I am now on the fence. I have a nice weatherpak type relay box to install, but would prefer not to if the LED setup is bright enough and low power consumption. Beginning to rethink my long term build. I am not an audiophile, and with LED headlamps do i really need any more than 35A output from an alternator. Found these on octanelighting. Appear stock. That might be a go for me as i dont like the modern looking LED lamps, but do prefer their effiency but want old skool looks. Octanelightings vehicle finder is rather clunky, but i was able to look these up for a 1974 chevy G10 van. Same 7" headlight.
