How does one change the brake lights on a 1985 Chevy Impala?
open trunk & you'll notice about 6-8 torx screws. on the top
of the light section. remove these screws, and tilt the housing
towards you. then you should see 3 electrical conections. some have
locks like a "medicine bottle top". twist & pull out
connection. the bulb should be there. there is 2 stop & tail
light bulbs, and 1 park light bulb, and the reverse light too. now
is a good time to check them all since you are there. some tail
lights are square and some are long, but the same procedure
applies. ( some have hold downs for the light section added in the
trunk to hold assembely also.) to remove these fastners it is
necessary to pull back carpet by the trunk lock, and you will see
them. if it dosent come out the first way you must remove these as
well. reverse to install. hope this helps.
