I'm sure you guys have noticed. I can barely see the electronic display during the day when I have my lights on. I like driving with my lights on during the day for safety. Anyway it's real annoying. Is there a way to not dim the display when the lights are on?

 

are you speaking of the navigation system / radio or dash?

 

I have noticed that the display for the cimate control is very dim but nothing else.

 

Sorry. Talking about the dash display where it displays your MPG, miles, etc. With the lights off it's bright. But when you turn the lights on it automatically dims the display. It sucks.

 

turn you light swithch all the way to the left and leave
it. all your lights should still be bright, allso make sure your adjustmant wheel is all the up.

 

All the way to the left is off. It does not have auto lights like some. The adjustment wheel for the dome light only adjusts the guages and the radio/dash area. It does not dim the "information center". Knowone else notices this. It really sucks. During the day I have to take off my shades and shade the display just to see it.

 

I can't be the only one who has this issue.

 

There's no way to keep the dash lights from dimming when you have the headlights on, it's a hardwired feature. The only way I can think to get around this is to go to the dealer and have them install / activate the DRL (daytime running lights) feature, if it exists on a super duty. I know there was one on my '01 F150, but that was then, this is now

 

Here's the relevant section from page 81 of the SD owners manual

Daytime running lamps (DRL) (if equipped)
Turns the headlamps on with a reduced output.
To activate:
• the ignition must be in the ON position,
• the headlamp control is in the OFF or parking lamp position and
• the parking brake must be disengaged.
Always remember to turn on your headlamps at dusk or during
inclement weather. The Daytime Running Lamp (DRL) system
does not activate the tail lamps and generally may not provide
adequate lighting during these conditions. Failure to activate your
headlamps under these conditions may result in a collision.

 

So I guess thats just the way it is. Maybe you guys with DRL don't have this problem because when the DRL activates it only turns the lights on and does not do anything with the information center lighting, dash lights or instrument panel lights. If you guys manually turn your lights on during the day you will see what I mean.

 

I checked my dash lights today. The Information center on my truck does dim with the dash lights and is adjustable with the adjustment wheel.

 

Oops. I just realized I posted here. I meant to post it on the 2008 6.4L forum. Maybe thats why knowone notices. Different display. Anyway it's on my 2008 F350. I'll post there.

 

Actually, you will see that it was moved here by the moderator from the 6.4 forum

 

I also find the diming very annoying. Also sunglasses will wipe out all of the displays. If you do a search on dash lights there is a post that says you can disable the dimming by unplugging a relay on the right side of the dash. It shows a picture of the right one to unplug. I printed the photo and am going to ask the dealer to unplug it the next time I get the oil changed.

 

Any chance you could post a link to that thread? I did the search you suggested (dash lights) and it returned 27 pages of threads!
