haven't seen much about led head lights or hid but for people who want to see what they look like here you go there maxxima 6x4 and yes they 're pricey mine for all 4 ran about 750 dollars they plug right in to the original harness might need to do some mods such as cutting the back of the housing out for the ballist to fit (only did it on the drivers side ) but other then the price they are really sharp and BRIGHT!!!!!!
