REGAL No low beam headlights

The light switch sends power to the dimmer switch, which then powers either the high beam circuit or the low beam circuit.
Therefore, if your high beams work, the fuse and light switch are good and it's either:
The dimmer switch (very likely)
An open in the low beam circuit (possible but unlikely)
Both low beam bulbs are burned out (highly unlikely)
Note: These postings often emphasize checking the ground path, but in this case the high and low beams share a common ground. If the high beams work, the grounds are good.
If you’re buying a new dimmer switch get one that will allow flash to pass. I made this mod on my car 20 years ago so I don’t remember the application but it was a Cadillac switch that was a direct replacement. I’ve also read that the newer G bodies might have flash to pass? Not sure maybe someone has part numbers to back that up.
High/Low beam switch
The high/low toggle on my turn signal switch broke the other day. i still had lights, but couldn't switch to high beams. Today i don't have headlights at all. I'm wondering if its because there might not be contact in the switch, like its stuck between high and low. if i pull the lever back...

Got my headlights fixed. The very unlikely was the culprit. Both low beam lamps were actually bad. Bought new lamps and now have lights.
Were they just old or something? Or more suspiciously, was there an electrical event that popped them at the same time?
Or did you have just one go out and didn't realize it then the other blew? I had that happen on my 2006 GMC truck when I thought it would be cool to put those Sylvania halogen bulbs in the capsules. One burnt out, but there was enough light to see and I didn't realize it until one morning on the way to work, the remaining bulb sh*t the bed then I had to putter down the road with driving lights when I had to dim the high beams. I soon figured out those Sylvanias weren't all that and a bag of chips. They died way too soon too often to be much good. Got GM replacement stock bulbs and never had to change them again. Not as bright, but they stayed lit.
Yes, I think they were the original lamps. One could have burned out without me knowing it and then the other burned out. The car only has 56,000 miles in it. My aunt bought the car new. When she passed away, my Mom got the car. When Mom passed, I got the car.
