Newbie here with a headlight issue that I'm hoping someone could help me with. This looks like a great resource chock full o' knowledgeable folks so I'm excited to get your feedback.
I noticed yesterday that my passenger side lowbeam headlights were not working. However, upon further investigation I noticed that the high beams were working although the low beams on that same side aren't.
My driver's side lights are working fine - high and low beams. And when i say that, it looks like I'm getting light from the same lamp, but with different intensities.
So I spent a couple hours looking around here last night, and it seems that my model (2003 Jetta GLS TDI Wagon) headlamp has a dual filament bulb which could explain this. I think. Not knowing how a dual filament works, I'm wondering if it's possible that the high beams could work while the low beams do not. In that case, replacing the dual filament lamp//bulb should do the trick, right?
If the dual filament lamp doesn't work that way, then my fear is that it's some kind of switching or relay affecting that one side only. Does that make sense?
This thread appears to be for models where separate lamps (a separate low beam lamp + a separate high beam lamp) where both should be on when the high beams are on, but I'm not sure that's the source of my problem if the driver's side is working. I'd feel comfortable changing the headlamps even if i had to take the bumper off, but doing this in the steering wheel is probably a bit over my head. I'd hate to go to all of the trouble to replace the lamp on the one side and learn that it's some kind of switch or relay in the steering column messing things up.
As an aside,I have a slightly embarassing question. While playing with which lamps were on/off during high and low beams & comparing the two sides I realized that don't know what the little round light under the orange light is for and when those lights should come on. I'm not sure it's relevant now (PLEASE feel free to give me the low down on that light though) but for whatever reason I always thought those little lights *were* the supplemental light that created my high beams. But it definitely looks like the big lamp on the driver's side gets brighter when the high beams are on & those little lights (on both sides) don't come on when I have the high beams on. I digress...
Another question: If it seems that the solution is replacing the one lamp (bulb), would you advise replacing the lamp on both sides while I have the bumper off?
THANK YOU SO MUCH!
