Default A Light Question

While driving or just sitting with the engine running, when I turn the headlamps off, the dash and radio lights get real bright! Why and what's the fix? Thanks.

I believe that you can use the little dimmer dial near your left knee on the dash...

That's a tricky one after 15,000 miles on 05 C-6 I still can't get it to work.

That is normal. When you turn on (or the system turns on) the headlamps, the instrument lights dim - by design. When off, they go back to bright - its day right. You can use the rheostat to turn down the brightness (at your left knee).

Control the brightness of the dash lights with the **** on the lower left side of the dash, near your left knee.

2006 owner's manual, page 3-19.
Turn and hold the **** clockwise to brighten the lights
or counterclockwise to dim them. During the day,
this **** will adjust the instrument panel brightness and
at night will adjust all interior lighting.
Be sure not to have this **** turned all the way down
with the lamps on during the day. Your Driver
Information Center (DIC) may not be visible.

No. Please read my other post. You should not be holding the switch in. That's how interior lights come on to stay and you wonder later who turned them on. Reread your owner's manual.

Me neither. The dimmer works with the lights on, but there's only one brightness setting with the lights off.

When the headlights are off, the system is set up to assume that you're in full daylight; in such a condition, it illuminates the dash at full brightness on the assumption that anything less would render the instruments difficult to see in the bright ambient light.

Sounds right, but do not really know for sure.

THIS IS EXACTLY THE PROBLEM! It's non-adjustable! The light is so bright it looks like it will blow a fuse.

AND THIS IS THE ANSWER! When you sit in the garage (running) or drive at dusk, and do headlights off, the system does not know it is dark. It goes to full (non-adjustable) bright. Thanks, as I thought I had a short in the electrical system. What a relief!

It should be noted that this intense brightness level on the dash, is much brighter than what is achieved by turning up the brightness ****, when the lights are on. Thanks again.

My car is away for the winter so I cannot check this.

If the light level bothers you a lot, try covering up the sensor gizmo on the top of the dash (the twilight sentinel) that might lower the intensity. You said you had manually shut off the lights, so this should not affect anything else.

Well, at least it won't blow a fuse, or the bulbs. Unlike the other lights the dash lighting is LEDs. Probably the bluish color of the LEDs is part of the reason it looks so bright.

Default dimmer ****

They are supposed to get brighter to see better in the day. My Acura is the same way.
