For those with Parking Lights Disabled

[jsoto]

With bulb source is your switchbacks ?

In my case, it's LED - but we're talking aftermarket rings - with turn/switchback function coming off the turns/parking lights. It behaves fine (switchbacks) with lows off.
The issues is the constant 12V (PWM) that comes into play with lows on.

I think turning off turn signals may shut/SHUNT the PWM 12 volt , but the PWM is causing the funky issues on the switchback rings. Regardless, I feel at the end of the day, I would still want running amber sides when lows are on (some level of sidelight visibility) than no lights on the side.
