It works out OK putting red behind red/amber behind amber..I thought the same thing, but they're not any darker, just a little brighter.
Twisting off the front round makers 1/4 turn will likely be a bit rough since they've been in place for so long and have accumulated some crude. Smaller hands make it a bit easier to grasp the front lens, (let's see how did RickOKC describe his...scrawny girl scout twig arms) and using a rubbery type jar opener thing can help.
OK, all you highly skilled handy people, look away and don't read this paragraph.....
Dome light was easily within my pay grade, just remove a little oblong festoon bulb about 1 1/4" long, Can replace with a flat wafer type LED bulb with the same type of ends as the festoon bulb...as long as the wafer part fits in the housing. I bought one that had 4 small LEDs within the glass tube of a festoon, but it wasn't nearly as bright as the wafer type with some higher power ones. It produces a great bright crisp white light, and you can angle the wafer to bias the light toward front, rear, center....(but entire cabin is still getting some light)

Pops in between the 2 pieces of metal with tension. I ended up using some small needle nose pliers to try to hold one end why I pushed/slid the other end up against the metal and get the tip into the small retainer hole. Word of advice...don't squeeze the pliers too hard or you'll bend/crimp/deform the metal end. But, happily, even after I goobered the metal end it still worked (and still works).I didn't get any electric shock BTW.
It was a good day!
I like the bright LED dome lights so much, when I traded in my 4Runner, I took out both LEDs and reinstalled the OEMs....Dave laughed at me.
