mmV8

Hi Guys, My 98 model LS400 has a current Drain issue I can't trace. If not driven for more than 3 days, the battery will be flat. Last time I checked, and removed all the main fuzes- it was still pulling 300mah. I check to make sure all the interior lights are off at night, and I don't even lock it so I guess the alarm is not activated. Does anyone have any ideas ? Also : radio lights - does anyone know if they are replacable mine have never worked. Chasing a drivers side mirror glass.
