Why does my headunit have to be so f*cking bright?!

So the factory radio in my 2014 R-spec drives me crazy!! Sometimes I like to sit in my car at night (with my headlights off and everything dark) and listen to the news or a good song that's on... my problem is that, even with the car off, the radio is so ****ing bright!! I cant stand it! I like to sit in the dark and I like when there's no lights on for anyone else to notice me! The bright blue light is actually blinding when I'm sitting in the dark and trying to look out the windows. I feel like a fish in a bowl because everyone can see my interior lit up, even with 5% tint on ALL the windows!! I even put 5% window tint on the radio screen... it helped a LITTLE BIT but not enough to even be worth the time!

Is there a trick or mod that I can do to dim the radio while the car is off and headlights are off (as if the headlights were on and the dimmer switch was turned down)??

Are you being a nit picky, but are you talking about the radio screen? You can dark it out. There is a display button push that.

Uhm two things...

The dimmer switch dims it significantly as well as you can turn off the blue with the Display button.

Thanks for the tip guys! Now that I can turn the radio screen off while the car is running or not running.... Is there a way to turn off the lights for the gauges while the car is running (without turning on the parking lights and using the dimmer)?
I have a remote starter and even when I take the key out of the ignition, the car stays running until I get out. I would like to be able to sit and idle while I chill in the dark too... is there a way to get rid of the gauge lights?

*Sorry if I'm weirder than you, I'm a country boy, not a city rat. I just prefer to sit in the dark at night*

Thanks again guys!

All you can do is dim them, you cant shut off the gauge lights

Yea that's dumb! They are so bright, it's ridiculous.
Some of this modern crap is nice... but I miss the old days! That's why I just can't bring myself to sell my '88 Stang!!

This has been an issue since at least 2011. My 2011 R-spec's LCD radio screen's backlight was always too bright even on its lowest setting, and so is my new 2016 base coupe's screen. Ideally these should vary as the dash light control is adjusted but they don't work off the dash light control. The dim button is a pain because any time you touch the volume or any other radio control, the too-bright screen re-illuminates. So you spend all your time being dangerously distracted at night by having to repeatedly reach for the dim button to shut off the bright screen....or just shut off the stereo system entirely (bummer!) This can be particularly problemmatical for drivers who have early, moderate cataracts (i.e. Just about everyone over 40). It's just not well thought out. Hopefully when they re-introduce the Gen Coupe as a 'luxury' sports vehicle they will fix this design (but by then it will probably cost well over $40K, so forget it!)

One of my biggest gripes about the interior (bk1 and bk2) is the interior lighting color they used.

"Blue light" puts the most strain on the eyes, because of this drivers are more prone to get tired, especially at night.
I have this problem. It doesn't help that I have 2 hour welding sessions, when I get time to make things stick together

Agreed. One of the things I enjoy most about certain KIA models is the red lighting. Its super easy on my eyes at night. Audi also uses red, while sister VW models of the same cars use blue. I skipped a Passat a few years back because of it.

A few years back one of the members here was working on complete red/amber light conversions, but I don't know if he still does it or even finished a single conversion.

Converting the LED's are easy. if you can solder smd it is simple to float the led's off and replace with red. Blue led's draw more current so there will be a current drop so be sure to remember to add more resistance if you do this conversion.

Sorry I'm a bit late to the "party." Have you tried the dimmer dial down on the left hand side of the dashboard, lower left from the steering wheel? Does that reduce is enough for you? I agree, with the dimmer turned all the way up, It's DARN BRIGHT! But I've been able to turn it down considerably. The switch on the middle dash does turn it black\off, buuuuuuut what if do want to read the screen\dash? :> Good luck.

If i turn off my headunit display and then during play, adjust the volume, the screen re-illuminates for a few seconds, and then Goes black automatically around ten seconds after i finish the volume adjustment...so at least it 'remembers' that i wanted to keep the screen OFF during play, so i don't have to keep turning the screen off after every volume adjustment. However, if i am playing MP3s from an inserted thumb drive, and reach up to skip to the next song, the screen illuminates but does not automatically go black - the automatic blackout feature appears to only work for volume adjustments.

Um, it's just you bro!
If I want to sit in a dark car (at night) it doesn't mean I'm about to kill someone. I means I don't want bright lights in my eyeballs after I've been adjusted to the darkness!! Not everyone is an attention whore who needs flashing lights and the "look at me, look at me!" effect. I prefer to be more stealth, incognito, less noticeable.... for the times that I want to be noticed, I can put on underglow lights, turn up the stereo, do a burnout, or just about anything!
Maybe I really just want to sit in my own driveway on a cold winter night and smoke a cigarette with the heater blasted and radio on without my kids knowing where I am.

I know this is an old question, and I'm late to the party but here's my point of view.

You are correct in the fact that blue light is stimulating. If the blue light is too bright it can be overstimulating, or irritating.

Yellow light, amber light, and red light are calming and won't induce a state of wakefulness. This is one reason why manufacturers use amber or yellow light for home night lights.

Quoted from ScienceMadeFun.net:

"Specialized photosensitive cells called ipRGC’s are located in the retina of our eyes. These cells are able to detect any light and send messages to a part of the brain that helps regulate the body’s circadian clock. This is the body’s master clock that helps determine when people feel sleepy and awake. These ipRGC cells are most sensitive to blue wavelengths of light and least sensitive to red wavelengths".

So in other words, if you want to stay awake, blue or white light for auto interior is the best - preferably on a dim setting so it's not overstimulating.

"Tiredness" and circadian rhythms are 2 different things.

Has anybody heard of eye strain from another other light, other than blue or white light?

With all due respect and not to belabor the point, below is quoted rom the same link you posted:

... "So, is all blue light bad for you? Why not block all blue light, all the time?

Bad idea.

It's well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood".

Actually your circadian rhythms and wakefulness and sleepiness are most definitely correlated. Certain light waves, at certain times of the day or night, can either induce or interrupt calm/sleepiness or alertness/wakefulness.

My point being was If your natural circadian rhythm is to be tired at night, and you need to stay awake at night while driving, based on the foregoing data you might be better off with blue light than amber or red. It also depends on how fatigued you are though.

I do believe there is a knob to adjust the brightness of the interior lighting. Perhaps it's the intensity that's most irritating for you. On the highest setting it is overly bright.

Having your "body" exposed to blue light, and having your "eyes" exposed to blue light, again are 2 different things.
It over stimulates the retina, and what does your eye does when they are over stimulated? It causes you to unconsciously squint, causing your cranial muscles to hold a certain position.
Now imagine holding that over the course of an hour or more; or even worse, having to re-engage those muscles every few minutes over the course of hours.

Think of it this way:
using lasers compare the light output of a red and a blue laser, both at 5 watts, as in 5 watts used to create the lasers.
A 5 watt "red" laser is just a laser pointer.
A 5 watt "blue" laser can actually burn things.

There is nothing above water that creates blue "light" naturally asides from splitting the spectrum from white light. All blues seen in nature is from "reflection" or "refraction", where all other colors are absorbed except the blue wavelength then reflected or split from white light and then having that reflect off of something.

Another thing is having the center console blaring all this blue light off to the side while driving at night. it distracts your eyes from where it should be looking at.

correlation does not equal congruency

humans didn't actually have the ability to "See" the color blue until recently

As I said previously it can be overstimulating.

I guess I'm not quite sure exactly what you're complaint is. Are you upset because the interior light is too bright? Are you upset because the interior lighting is blue? Are you asking for a way to somehow change the color of the interior lighting? Or are you ljust looking for other people who are upset about the interior lighting so you'll have others to gripe with?

All-in-all the Genesis Coupe is what it is. If the interior lights irritate you to that extreme and it's not changeable or adaptable to your liking then just.sell the car and buy a vehicle you like better! Why live with something that constantly irritates you?
