start with taping around the stock headlight beams.. this will be for alignment of the new headlights.. then simply remove the 3 screws.. they are very obvious.. the headlight should still feel snug.. reach in behind the headlight bulb and push straight forward and out.. DO NOT ATTEMPT TO PULL OUT BEFORE THIS POINT..

it should become loose.. now the hard part is finding a angle for the headlights to come out.. they should be stuck between the bumper and the point of the fender.. GOOD LUCK.. this takes about 30 minutes tops..

 

its alot easier to remove and put back in the headlights if you remove the bumper. the first time i did it like you but i scratched the crap out of the bumper trying to figure out how to get the right angle to remove the lights.
the second time round i just removed the 5 screws holding the bumper in and removed it. A million times easier after that!!!!

 

+1 especially if you have to wire Cedias.

 

also for painting the reflectors. nevermind that moving the water resevoir nonsense.

 

Id have to agree

 

That step is necessary if you own an 04+
