i needed some more light than the AAA battery power led comes fromthe top of Toyota ABS Hard top...
so i use the 12v from battery, along chassis, and then in the tail light cavity to power on a 12v led light strip
see there https://www.newhilux.net/phpbb/viewtopic.php?f=121&t=31885&p=435486#p435486
i use some 3d printed support to make "curve" the led strip at the bottom angles of the tub...
add also some "VHB 3m Style" bi-adhesive because i don't trust the led strip bi-adhesive...
with an illuminated button using a pre-existing hole in the rear light wall.. (just enlarge from 9,5mm to 12 mm) so i can find it immediately in the dark.
hope you like it..
