Hello All,
pretty new here, tried searching but came up empty. I just picked up my white is250 isf, I was wondering what kind of lights the interior lights are? trying to upgrade to the leds at least over head

 

You must mean an F-Sport, because the IS-F only comes in one flavor... But, to answer your question: I'm not exactly sure what sizes the stock interior lights are, however iJDMToy (a CL vendor) sells packages for our vehicles that include the majority of the lights you'll need.
