Default 561 vs 563

The footwell lights on the bottom of my car are P/N 563 according to Ecklers. I found a brighter one that is 561. Are they interchangable due to the # difference? They are LEDs. Just wondering.

Thanks

If the replacements are brighter they may also be too hot and melt the plastic lens. Maybe you can find a bright led replacement.

Oh, they are LEDs. I was just curious if these two part #s were interchangable. I have been looking for along time but never found 563. Just 561. Thanks.
