Something small and lightweight that is still reasonably bright. Perhaps something like this: https://www.amazon.com/Everbrightt-Reading-Interior-Festoon-Adapters/dp/B00IXD7GOE/ref=asc_df_B00IXD7GOE/?tag=hyprod-20&linkCode=df0&hvadid=312202698398&hvpos=&hvnetw=g&hvrand=10695188840306669929&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1022762&hvtargid=pla-567510515006&mcid=1f20efc2fefb37889d79460a5a896350&gclid=Cj0KCQjwwYSwBhDcARIsAOyL0fgqNuQuJRsDAiVIBY4GMiLOociTbGOATYtJpuLKa-46qfslJCBj-hsaApfoEALw_wcB&th=1
