Ok I have done the "big 3" upgrade and an upgraded wire harness to the headlights so I'm getting maximum voltage to the bulbs and the lights are still slightly dimmer at idle in drive, foot on the brake.
So, do I:
1. Accept it because that's how it is?
2. Optima battery? (Parts counter dude said these will stop the dimming)
3. Upgraded higher-output alternator?
Thanks in advance.
