EDIT: Sometimes reading carefully is better than writing BS.

I noticed after writing this post that you've already tried r_skip_glare 1.
Sounds rather odd that it just tones down the effect and doesn't completely disable it.
But you might also want to try r_skipEmissiveGlare like i describe below. EDIT END.
I've heard that most console commands in the newest patch for Rage are disabled, which means you might not be able to change anything on the fly.
But we should just try it.
Again: I don't own the pc steam powered version so i'm digging in dark here.
First we'll try if the respective console commands work and are not disabled:
1. Put "+set com_allowConsole 1" in your steam launch options to enable the console if you haven't already done that.
2. When the game is running and you're looking at the area shown in your pics, open the console (does anyone here know the key for that?).
Type :
r_skipEmissiveGlare 1
and press enter
if this doesn't help reset it by typing:
r_skipEmissiveGlare 0
and press enter to reset it to the default value.
and then type:
r_skipGlare 1
and press enter
if this doesn't help reset it by typing:
r_skipGlare 0
and press enter to reset it to the default value.
Judging by the name of the variables, both will completely disable glare calculations. Sadly, i haven't found any commands that change the parameters but it might be better to switch glares completely to "off" than to be permanently blinded by them.
Secondly (if console commands don't work) we'll give modifying rageconig.cfg a try:
IMPORTANT: BE CAREFUL NOT TO CHANGE ANYTHING ELSE APART FROM WHAT I SAY IN THAT FILE OR IT MIGHT CRASH OR GIVE UNEXPECTED RESULTS! IF YOU MISTYPE ANYTHING OR CHANGED ANYTHING ACCIDENTALLY, CLOSE THE FILE WITHOUT SAVING AND TRY AGAIN.
Search "rageconfig.cfg" in your Rage folder and subfolders.
When found, open it up with an editor and search for
seta r_skipEmissiveGlare "0"
change the "0" to "1" and save the file and start the game and go to the area shown on your pics.
If this doesn't work:
Quit the game and open rageconfig.cfg
Reset the variable you just changed back to:
seta r_skipEmissiveGlare "1"
and search for:
seta r_skipGlare "0"
and set it to "1".
Save the file and restart the game and see if it helped.
If not, reset it to the default "0" like above.
I hope this works...
