measure the ground potential at the display...perhaps the instrument panel can use another ground strap...if the current one is rusty or messed up~

no kids here U don't understand . these led odometer has nothing to do with indicator light dimmer. They automatic dim when you turn head lights on. but they dim even if you place switch in the automatic headlite mode with the lites off. Ford said no adjustment. it is ok if I just work headlite manually. Again this has no associaton with the instrument lighting or dinng control. I am thinking the power supply for these has dropped lower.
