[OXO cube]

hi guys 

in the past i have wired LEDs into my cars for head/tail lights with great success
but i like the idea that the lights could remain illuminated temporarily after a deslot 
is it just a case of introducing a capacitor into the circuit ?


has anyone any experience or tips regarding this 

i know there are light kits available on the market , but trying the DIY route is part of the hobby imo
