My problem occurs while im simply driving down the road. My headlights, dashlights and all other lights will dim for a while then all the sudden they go back to normal brightness. I noticed that if im at a stop and give it throttle and it hits vtec they will brighten if they are dim and also if i flash the high beams they will go back to being normal if they are dim. What is going on here, could it be the alternator, i did a test and its normal any other suggestions?

 

Check your grounding points. That is a symptom of poor ground distribution.

 

And your battery terminals. Make sure they aren't corroded.

Had same prob. Mine was the battery.

 

I've seen this happen as a result of a bad ground from the alternator. To be on the safe side I would go on down to your local autoparts store and have them
test the alternator and the battery just to make sure they are in working order too.

 

Ok thanks for all your inputs ill let yall know the outcome
