BACK UP LIGHTS

[putneyflash]

First of all thanks to all who answered my question about all the
driving lights, backup lights and docking lights staying on. it was as
most of you though the security switch in the bed room.
My back up lights don't work i tried to gethe bulb out and it won't
budge. Where can i get the light?
also i have never seen the round white lights work, i don't know what
they do.
thanks again
