Reach beind the headlight and just unscrew the cap that holds it in. However don't touch the new bulb with your bare fingers or you will drastically shorten the life of the bulb.

What would cause the low beam headlight not to work when all other lights work?


If you have standard halogen bulbs:

  1. Burned out light bulb; or
  2. Fried wires between the dashboard wiring harness and the headlight bulb connectors; or
  3. Fried headlight bulb connectors.
If you have HEI emitters:
  • Failed ballast.

Why doesnt headlight work on low beam left side?


Bulb may be no good as in headlight bulbs one filament can go leaving only either low beam or high beam operational on one headlight so change the bulb first on that side other than that could be power related

Left headlights


Check your connections at the wiring harness going to headlights for corrosion, sounds like high resistance somewhere, also make sure your ground wires are secure. It wouldn't be the alternator or the battery would be dead and not start the engine. Also shouldn't be any condensation in your head light assembly's or will cause bulbs to blow prematurely.

I have a 2006 civic SI. DRL indicator is on, driver side low and high beam ok. Passenger side low beam ok but DRL and hi beam not working. Any help is appreciated.


When either the high or low beam light is out in either side, DRL (daytime running lights) indicator will come on. When one bulb goes out, that's a clue the opposite bulb will burn out soon, so its best to replace both bulbs. If it was a fuse issue, both left and right side would be out. If driver side is OK but passenger side is not, then its a bulb issue. A 2006 Honda civic takes 9006 (HB4) low beam bulbs and 9005 (HB3) high beam bulbs. Cheapest is online from Walmart site-2-store. After procuring, wear latex, vinyl, or ANY gloves to keep your (corrosive) oil skin from coming in contact with headlight glass bulbs. Your skin oil will chemically react and cause shorter life span on glass bulbs. Instruction don't tell you this, so you handle with your hands, then need to replace bulbs 3 years later instead of 5 years (or more) in the future. With gloves on, pop the hood and look behind each headlight. Turn counter clockwise to unlock headlight bulb holders. Its a quarter to half turn to unlock bulb holder lock. Replace one bulb at a time so you don't confuse high beam from low beam. The wire has a tab you need to lift to pull out & disconnect wire connector. You might need a slim narrow-**** (NOT phillips) screwdriver to lift the tab; or use your house key. Snap the wire connector to the new bulb, then twist into headlight housing to secure bulb holders, then move on to the next bulb to repeat the procedure. Pict below, 9005 high beam is on the left, 9006 low beam is on the right. Handle by grasping the plastic base, not the glass bulbs. The raised potrusion on the bottom center is where the tab locks onto wire connector. Replace all 4 bulbs now, but in the future, its likely the low beam will wear out before the high beam. In the future, replace only the pair, not all 4. The factory installs inferior bulbs that go out sooner, hoping you'll take to dealership and they ******** you with higher parts-n-labor fees. As opposed to Walmart online site-2-store, it would cost you AT LEAST triple in parts & labor from dealership to replace all 4 headlight bulbs :-(

Need to change the left side low beam headlight.


It might be hard to get to like that. You will see a silver metal bar with a 90 degree angle at the top that goes straight down behing the headlight assembly, which you can pull up on. It holds the headlight in. Once you pull this up pust the headlight slightly sideways as there is a plug holding the headlight in at the back, then just pull forward to give youself space to work. Clip off the two clips and slide the back cover off then you can change the bulb out.

Left brake light stays on constantly when headlights are on. When headlights are off, left brake light is dimmer than right brake light when brakes are applied. I did recently change the brake bulb. ...


There is a shortage some where at the brake bulb and low beam holder. Take off the bulbs and inspect carefully those losing wires attached to the ends can cause the problem. Good luck.

When low beam headlight is on passenger sign is


Try this to eliminate new bulbs for both sides:
With a partner behind the wheel:
PULL out the bulbs one at a time. Keep them plugged in. While you are holding the bulb - have your partner click and HOLD the High Beam Selection. This causes the Low Beam and High Beam filaments to both go on and stay on.
Check both sides this way.
While the bulbs are out, look at the filaments that did not illuminate. Are they broken, bent, or have indications they are burnt out?
You can also change to bulbs (left to right, right to left) and recheck using the above method of holding the high beam selector and checking the filaments.

Low beam not work !!


replace the headlight bulbs. Usually when the bulbs blow out the low beam blows out first, but the high beams still work. If you want and need both low and high beams to work then replace the headlight bulbs with brand new ones and I garauntee that both low and high beams will work
