I have pulsating headlights/overhead lights/tail lights. Bright-dim-bright-dim. The car's lights looks like an emergency vehicle.

The car did not do this until I rebuilt the alternator using an eBay rebuild kit, all aftermarket parts. I think I need a Delco voltage regulator, Two list for my car, which one is correct?
