How do you change a license plate light bulb on a Lexus IS 300?
pop off the carpet trim from the trunk hatch. there are three
8mm or 10mm nuts that hold the upper license plate trim containing
the bulbs. the center one also holds the trunk latch. remove these
and pull the whole assembly out. the bulb holder twists out.
replace with a 194 bulb. use LED 194 bulb for longer life and
brighter light. you can also get different colored bulbs to
customize @ www.superbrightleds.com
