My brother just installed the Celica Door Light by Burialc2 (Blue Color) on his SS2 JDM Celica 
It is custome LED Panel replacing Factory door bulbs and can be done in the way you can find below by Burialc2.
The fit was perfect (makes you think that it is factory made)
Few photos of the interior and also links from Burialc2 Projects website.
