Yes the idle drops a little.when i turn the lights and also the heater.but sometimes the lights become dim and when i press the accelerator it becomes bright again
Actually when i turn on my headlights my dash lights become a bit dark.and sometime when the car is idling at 900rpm the headlights are dim and when i press the accelerator then light become brighter.no sound system.dont have high engine mods too.just have aftermarket ignition system.
