Hi guys i need help.Any one know what might cost this dimming of gauge meter and every light that i turn on even the head light also are doing it? when driving at night all the light work ok but when i got on the break it seem like every light that's on got little bit dimmer but when i let off the break all light got bright again.

 

Sounds to me like a earth leak somewhere. Check your rear light for bad earthing or contacts.

 

i was going to say the same thing, i had the same issue with my old prelude

 

Alternator?

 

Could be the voltage regulator to the alternator as well. Check all the wires that go into the alternator and make sure they are in good shape.

 

Loose ground strap, as soon as you hit the brake pedal, the brake lights try to get ground through the rest of the lighting, thus dimming them. Check ground straps, if need be give the brake lights a seperate ground, to by-pass the problem for now...
