I'm looking for feedback on what folks consider the best halogen headlight bulb these days. I'm looking to replace the ones currently in my fleet's 2011 Ford Fiesta. It's headlamps had really deteriorated and gotten very, very cloudy. I spend hours yesterday restoring them with a Sylvania kit which produced nice results. I'd now like to update the old bulbs to something that will provide the best night visibility achievable. Sylvania SilverStar or SilverStar Ultra? I'm looking for a plug-and-play replacement and am not considering a HID retrofit or anything like that. Thank you in advance for your input!
