My (2001) headlights are always the dimmest of any car around me on the freeway. Is this a common issue with Prii? Yes, my lenses are clouded, but even when I clean them up, they are still dimmer (and yellower) than the cars around me. Is this a possible indication of a problem with the electrical system? Any recommendations for headlight bulbs I could try that might make them brighter. I can't remember what bulbs are in there now, but I think they are just stock replacements. Thanks,
A good place to start would be to have the 12V battery and it's connections checked; also the charging voltage when in RUN mode.
12v battery is near new. Battery voltage is 12.88 volts with car off (fresh from commute home), and 13.8 volts when running. No other electrical issues.
Next would be to check the voltage at one of the lights. Battery voltage is only part of the story; if there is a loose or corroded connection somewhere along the way, the voltage at the lights might be down. Bad grounds are often the most elusive. Then, hopefully someone who knows what bulbs that model uses will chime in with replacement recommendations.
