Here is what I did to replace my burnt-out radio display lightbulbs with LED’s on my 2003 Toyota Matrix XR.
I am sure by now everyone knows how to remove and disassemble this radio from the Toyota.
Enjoy!

1. Purchase FLAT LED’s from Amazon
2. Note resistance required for voltage
3. Purchase required resistors from Amazon
4. Attach TWO ¼ watt resistors to FLAT LED as shown.
NOTE: POSITIVE resistor lead sticks out a little further.
5. Top view of assembled LED assembly.
NOTE cut corner indicator.
6. Burnt out lightbulbs removed.

Display does seem a little bright and "hot spots" from the 3 LED's. I guess I could have chosen a higher resistor value say 4k or 5k to reduce the intensity. Maybe "frosted" tape placed loosely over the LED's or maybe even a cotton ball in the cavity of the display to diffuse the "hot spots" of the LED's.
