A multi-meter is a good tool to have for troubleshooting electrical issues, and any good technician needs to own one, (most of us have more than one) but you really need to load test your battery and charging system if you suspect either of those to be an issue and a multi-meter isn't really the right tool for that.

However, the problems that you were describing in your original post seem like they may be due to the installation of your aftermarket lighting. If the installation was done poorly using connectors like T-taps that pierce the wiring insulation, those can eventually cause problems like you are describing with the interior lights. Especially if a previous owner tapped into the wrong circuit.

I think you are correct in suspecting that the Valenti LEDs are going bad, but that wouldn't cause the problem with the flickering interior lights. You should closely inspect all of the aftermarket wiring that has been installed into your car. You can always unplug the taillights from the car and continue to troubleshoot to see if the flickering goes away, but I will bet that there's something else causing that issue.

I changed the interior LED that was installed by the previous owner and now the problem is gone, so got that taken care of.

I have however noticed the left HID flickers usually whenever i don't give enough gas and the car is about to stall, so that makes me wonder if the battery is at fault and going bad.

The headlights are stock, they're the original ones that came on the car from the factory and they have HIDs and led DRLs on them, these ones to be precise:

So other than the Valenti taillights there's nothing aftermarket on the car
