After much research, and little info on "how-to", I replaced both stock 9006 low-beam bulbs on my 2004 Accord. Despite much info on removing fenderwell splash shields, I was able to open the hood, and reach the passenger side harness, remove plug, twist and remove bulb and reinstall- no problem. Driver's side required removing the battery, but same procedure. No problems, no cuts or bruises. Owners manual is unclear, Hayes 2003-05 Honda Accord repair manual is wrong, and the dealer charges $29.95 per bulb installed. Took me 10 minutes. Tried to save the radio settings with a 9V battery in the power plug (memory-saver) but that didn't work. Still needed to put in the radio anti-theft code, reset all the stations and time. Not sure on the other settings (PCM idle learn procedure??)
