Does anyone know how to access the tag lights on the Ascent? I'd like to change mine out for LEDS but can't figure out how to access them without doing damage.
If you change them to LEDs, do you need to address the resultant flickering due to the different resistance the same way we need to address the headlamps when changing them to LEDs?

I don't think the rear LEDs will flicker. I've swapped them out in previous vehicles with no problem. I have yet to do it on our Ascent, but I would like to in the future.

I don't know how the halogen headlamps work in the Ascent, but if LEDs flicker when swapped in, then the headlamps are probably pulse-width modulated (PWM), which means the electrical current is actually pulsed on and off in rapid succession. This is a very common way to drive high beams as DRLs. The current is modulated to be half on and half off (for example), and the lights will appear to burn at half the intensity. I'm not sure that'd be going on with the Ascent's halogen headlamps (they're not used as DRLs, right?), but flickering LEDs is a symptom of that.
