Hi! I've been a silent reader in the forum for quite some time now. Hope everyone here is doing great. I just recently installed a new head lights and I noticed weird noise from my audio system that may be caused by an electrical problem. Is it possible that the new headlight drew a high current and cause a voltage spike to my audio system? I'm unsure if the power wire of the accessory produces the noise and ground. Will a capacitor help? Would like to get your recommendation on what capacitor to get.
