how do i change the low beam lightbulb on my 2005 mazda 3
There should be instructions in the owner’s manual. Usually the bulbs are removed from the back of the headlight assembly, under the hood.
DO NOT touch the glass part of the bulb when you install the new one. A finger print will shorten the life of the bulb.
i no longer have the owners manual
Then you’ll have to open the hood and figure it out. If it’s a tight fit behind the headlight assembly you may have to remove things that are in the way. Some bulbs are pretty easy to replace, others not so easy.
I can change the bulbs on my Subaru without moving anything, but on my Acura I have to remove a piece of the air filter plumbing to reach one of the bulbs.
I just heard that the new Honda Accord headlight bulbs have to be removed through the fender liner!
The clerks at the auto parts store may be willing to show you how to replace the bulb.
Many owner’s manuals are available on line. I didn’t “sign up” as I don’t have a mazda, but it appears to be free. Look here: http://www.mazdausa.com/MusaWeb/displayOwnersHome.action?bhcp=1
OTOH, if you can see the backside of the headlights under the hood, either in plain view, or by lifting a plastic panel, it should be a fairly straight forward situation. There will be a keeper of some sort, then the old bulb will have to be turned about 1/3 and pulled out.
Pretty soon the headlight bulb will hafta be replaced by removing the whole headlamp assembly, which will require the front bumper to come off. Like others have said, today’s headlamp assemblies are made for looks, not function.
I long for the days when all it took was a new sealed beam light (only a couple of kinds) and a screwdriver. In five minutes you were done and it was cheap.
