How do I replace a low-beam headlight for a 2002 Honda Accord V6? The passenger side is easy to get to, but the drivers side has a jug right in front of the bulb.

The usual cause is a bad ground.
Check the ground with a test lamp.

There are two fuses that must both be good for the passenger low beam to work. Fuse 4 and fuse 6. If they're good, you should see battery voltage on the red/green wire in the bulb socket.

I would check for the groundwire continuity

The high beam continues to work on both sides...I pulled the Driverside headlamp fuse and then both left and right beams lit up but very dim.

Sometimes, Honda's have a fuse for each headlight. I would start with checking those.

This is usually caused by a failed front control module as this unit controls the lighting on the vehicle!

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.

For Audi A4 the fuse box is located on the left side of dashboard behind a plastic cover (for left hand steering wheel vehicle). On inner face of the plastic cover you will find the fuse diagram.
First fuse on first row from left upper corner is Fuse Nr.20 = F20 (15A) - RH headlamp low beam, headlamp adjustment.
First fuse on second row from left upper corner is Fuse Nr.21 = F21 (15A) - LH headlamp low beam, headlamp adjustment.

I just replaced both low beam headlight bulbs on my 2005 Honda Accord. After reading the owner's manual and trying to remove the wheel well inserts (and breaking a couple of those clips in the process), I gave up on that approach and was able to change the passenger side and driver side low beam bulbs from the engine compartment under the hood. On the passenger side, fit your arm between the front of the car and the hose that is above the headlight. You should be able to reach the bulb, disconnect the electrical connection, turn the bulb 45 degrees counterclockwise to remove it, insert the new bulb turning it 45 degrees clockwise to secure it in the hole (be careful not to touch the bulb), and reconnect the electrical connection. I loosened the 3 screws that secure the bulb to make it easier to put in the new one, but that probably isn't necessary. My hand was scraped a bit doing this, but it was not too bad. On the driver side, remove the battery hold-down clamp (there is no need to disconnect the battery connections). Reach into the fender (shine a light there so you can see the bulb connection) and you should be able to reach the bulb and replace it similarly to the other bulb. You may have to move the battery slightly to get your arm in there. Replace the battery hold down clamp when you're done. I accidentally dropped the old bulb in the wheel well, but other than that it went pretty smoothly. Good luck.

you say you replaced both bulbs, you mean right and left or both the high beam and the low beam on left side?could be a bad ground for the left headlight. there should be some ground wires there near the headlight, LF corner under hood. without a wiring diagram here at home,I am not much help.
