I am so happy to finally have a clear WIN for the awful OEM backup/reverse lights on the 4th Gen. Buy this:

I had tried another set of aftermarket bulbs and read all the posts here on the forum - most of which are of people giving up and going to auxiliary lighting mounted on or under the rear bumper or other creative places. No doubt you can get some serious beam on the rear by going that route, but I wanted to stay near-stock if possible. I read the reviews on the LUYED lamps and gave it a shot. The difference is seriously amazing. I'll try to take some demonstrative pictures tonight and post, but I'm guessing I'm getting 400 to 500% better light than before. Basically, I could not see anything substantial with the stockers or the second set of bulbs I tried - I used the brake lights to allow me visibility behind. This Luyed set cured it. The biggest surprise to me is how well the light spreads out 360. The way the 4runner lights are placed is just maniacally awful - too small, too low, too far from the corners. Compared to my old Camry, which lit up the neighborhood, the 4runner was lights out.
Not anymore.
I have no financial interest in LUYED and nobody asked me to post this. [though if they are looking for investors, I may need to do that]
