62 Buick Headlights

Hello folks,
Quick question. On one side of my car the headlights only work for a high beam, not for a low beam.
Are there two bulbs inside the headlamp one for high and one for low? Do I need to replace that entire thing or just a bulb?
Thanks in advance.

4 headlight system . . . 1-high beam, 1-low beam on each side
2 headlight system . . . 1-headlight assy on each side, housing a dual-element illuminator . . . 1 element for high beam, 1 element for low beam. Each light is about 7" in diameter whereas the 4-light system headlights are about 5.75" in diameter.

Providing there are NO wiring issues, replacing the un-lit bulb would be the first thing to do.

For good measure, check the lamp wiring harness as there's usually ONE ground wire (black) on EACH SIDE, whether single or dual lamps on each side.

Enjoy!

Yes, the low beam headlight has two internal filaments, one for low beam and one for high beam. That's why the low beam bulb has three terminals and the high beam bulb only has two. You need to replace the entire sealed beam, the filaments are not individually replaceable.

Hello, thank you for the responses.
I had taken this picture earlier to show you all what I meant. I see, so I need to buy a new beam.
Any advices or ideas about where I should find a good one?

Thanks again, appreciate the help.

Any auto parts store should have them. For example NAPA has them as part number 4000 for the standard Low Beam bulb and H5006 for the Halogen.

Oh that's great news. Lately I've been having a hard time finding the right parts for my car. That's great news that Napa will have them.

Thanks!
