Dash lights fluctuating brightness
Good morning and hope everybody had a good Christmas.
I tried to search posts for this problem but didn't come up with the result I wanted.
I thought I saw a post here at one point on the dash lights becoming brighter as the rpm went up and dimmer at idle.
Is there a relay or some sort of voltage booster I can add? Dash is all stock.

do the 3G swap and it will eliminate this. The pick a parts have plenty of donors for this. costs about $30.
first 3 link here cover the swap, https://www.ford-trucks.com/forums/1...l#post12243508
also, clean and secure all grounds.

check headlight switch
Do make sure to check the headlight switch. There's a spring that goes all the way around for adjusting the brightness and the spring is prone to breaking but with all the bouncing may still make a connection. My dash lights were doing just what you described and it was that spring on the headlight switch. Search the threads about removing as there are a couple of tricks to get the **** disconnected, etc.
