Just a quick one, can someone tell me for certain, when I flash someone (2001 Impreza wrx), as well as my main beam flashing should my dipped beam flash as well? I have a WRX where someone has bodged the wiring in order to fit some different headlights. Initially it went to the garage because the passenger side dipped light and main beam light were [considerably] brighter than the driver side ones. That has now been solved, but the mechanic was unsure as to whether all four lights should flash when you flash someone?

When you flash, it should be just the high beam except if you have bi xenon headlights.
