I didn’t buy a kit but used Luyed LEDs from Amazon. I played around with different brightness for map lights because the first pair were too bright. A lot of the lights use the same bulb so I bought in bulk. My wife also has a Toyota with the same bulbs so buying bulk was cheaper per bulb, plus I have some spares.
Something to know about the kits is you usually only get two dome lights. The limiteds (and maybe others) need 3 total dome lights. Which is another reason I didn’t buy a kit.
