I drive a 96 Subaru Legacy. What does it mean when one of the high beams is dimmer (less light output) than the low beam? I am using a brand-new bulb. It’s not an adjustment issue because I was looking at the bulb when it was outside of the housing and it clearly gets dimmer when you switch to brights. However, they are equally bright when on low-beam, so I don’t think its just a crossed wire. ---

Check the voltage going to the bulb & for corroded wiring. ---

The dimmer switch and the headlight connector are the prime suspects…A bad connection is dropping the voltage…
