67 Fastback Exterior Lights Operation
 

Hi All.

I was working on getting my car ready for safety check & in the process of testing all the lights, I noticed that once the headlights are turned on (either hi or lo beam), the front marker lights turn off. If just the running lights are on, then the front marker lights are on. In either scenario, the turn signals work normally. I was wondering if anyone can confirm that this is normal operation? Usually, if there is a problem like a bad ground, you would see some weird behavior between 2 lamps. This looks like its supposed to be this way.

Thanks!
