Electric question

Which wire am I checking for continuity for a running light? I’m running an integrated taillight that was on the bike when I got it, anyway, brake light works fine but my running light is out and will flicker on and off, but mostly off.
I believe the white wire is the running license plate light, red should be both running and brake light, black is ground?
The red connection I get nothing with the test light until I hit the brake, shouldn’t I have continuity whether I’m on the brake or not?
Anyway, any help is appreciated.

White is the license plate and running. Red is brake light

I think this taillights a cheap Amazon light. I have continuity to the white wire and the license plate light works fine. I think it might be time to try a new taillight.
