I just replaced the bulb in mine with a cheapo led one that was supposed to fit our old 04 armada. It didn't fit so I made it fit, sorta. It's 1000 brighter and more useful than the stock light bulb. I haven't bothered trying to fit something over the rear seat. My phone has a light if I'm that desperate.
