Headlight not working 2008 beetle, bulbs all ok

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

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 :-(

Replace the headlight bulb.

Instructions

1. • Turn the headlight switch on and inspect the headlights. Make sure to check both low- and high-beam lights, and then note the position of the bulb in the headlight assembly. Low-beams are in the top cavity of the assembly and high-beams are in the lower cavity.
   • 2Turn off the headlight switch and then remove the keys from the ignition.
     
   • 3
     
   • Open the hood and locate the seam to the headlight assembly and the side fender. Locate the headlight assembly release lever and push in on it slightly to unlock it and then pull it all the way up until it stops.
     
   • 4Place a blanket or pillow on the ground in front of the headlight assembly. Push the assembly outward from behind with one hand while being ready to catch the assembly with the other. The New Beetles use an adhesive sealant to protect the back of the headlights from exposure to moisture, so you'll have to give the assembly a push from behind.
     
   • 5Pull the wire harness plugs off from both the high- and low-beam blades of the respective bulbs.
     
   • 6Place the assembly on the blanket or pillow. Release the wire clip to the faulty headlight and then remove the headlight bulb.
     
   • 7Open the package of the new H1 bulb replacement without touching the glass portion of the bulb with your bare skin. Oils in human skin will damage the bulb. Handle it only by the metal base of the bulb insert.
     
   • 8Insert the new bulb in the appropriate headlight-assembly cavity and reattach the bulb retaining clip to lock the bulb in place.
     
   • 9Lift the assembly up and plug the wire harness plugs back into the respective blades of the bulbs.
     
   • 10Push the headlight assembly into its cavity, but before locking it in place, check the lights by turning on the headlight switch.
     

I believe vw uses 4 fuses 2 high beam, 2 low beam, see if high beams work,check for a blown fuse. Another possibility is a corroded wiring harness that plugs in behind the headlight. Unplug and replug the headlight socket a couple times to clean corrosion.

If your highbeams are working fine, you must be referring to your low beams not working I would simply check the 2 bulbs and make sure the low beam filament is good, theres a strong possibility that your BOTH low beam filaments are bad and require replacement of both headlight bulbs to get them working again its a very simple repair.....

it may be a blown fuse on the low beam circuit,check the fuses,if the fuses are OK check the bulbs.....hope this helps.....cheers

if the high beams function when holding the passing lever, you know the bulbs and fuses are good, the bulbs do operate. the passing lever bypasses the headlight switch on the dash. replace the headlight switch, and be prepared to also replace the connector for this switch, since they had a tendency to melt.

on these cars if 1 of the bulbs blow out then you will have to replace them both because they wont work. replace both headlight bulbs and they will be just fine
