How do I replace a headlight on a 2000 Honda Accord?

HEADLIGHT REPLACEMENT

1. Remove the front bumper
2. Disconnect the connectors (A).
3. Remove the 5 mounting bolts (B), then remove the headlight assembly (C).

I suggest you check the headlights if its still okay, then check the ground connection, or check your dimmer switch.

Sounds to me like you need to reset the headlight housings... maybe they are vibrating very badly. ... OR, easy fix, get NEW headlight housings on EBay and install.

First, you might check your dimmer relay fuse (under hood fuse box, number 2, (7.5A).
Hope it's that simple (if not, you will have to have the relay tested, and possibly replaced; probably something you don't want to try yourself.)

remove the hose ...this is to the radiator correct just make sure the motor has not been Running or you will get burnt also use a pan to collect the antifreeze and refill the radiator

open the hood and reach behind the lights. There should be a ring, turn this plastic ring until it stops and the bulb should come right out, theres probably a better explanation in your manual

Check the earth wires have a good connection and are clean..

Its actually pretty straight forward. Disconnect the headlight. Then their are two bolt on the top the the headlight. Remove those then remove the wheel of the car. Then their are three more bolts bellow the headlight All three facing from the outside of the fender to the center of the car.

Then once you have those 5 bolts out. Pull the headlight forward and up. Their are two tabs that go into the fender.

Just unscrew/twist the bulb holder ,about a quarter trun, at the back of the headlight unit.

what i suggest i can suggest is, buy a clear sealant, and seal the sides of the headlights.

the reason why is air can creep in tha lamps that's why it gets moisture (foggy) and dirty.

hope it helps.
