There is enough room on the strip to solder in new LEDs (red arrows) along with their 220R resistors (green arrows) on the original solder pads.

Use resistors in the 0603 package to fit them into the available space.

Desolder the original 22R resistors and short their pads with a thin wire.

Verify that all three new LEDs work by connecting a 5V power supply onto the "A" and "K" pads on the strip.
