color them a sharpie. its in the projects. looked like it worked pretty well. then if you want to clean em again you can put them right back to stock. I recently found out that cologne will dissolve a lot of things off smooth surfaces that cleaners wont.
My mistake. Replaced them with hyper-whites a while back and haven't really thought about them since. 194 is the glove box...I guess that's what I was thinking of. Sharpie or order some LEDs online.
