My break lights till work but my running lights do not I checked the fuse and it looks fine I mean even though its the same bulb could a bad bulb be causing this and it is happening with both tail lights.
You can get a multimeter under $20 to test the bulb, or by a new bulb.
If it’s not the bulb, then you have a spare.
Yes, both running light filaments could have broken at the same time perhaps when driving over a bump.
This happened to me once with headlights.
One evening went to use them and both out.
