After a bag of groceries hit the inside of my trunk the warning light came on for the rear lights. After hitting just the right spot again, it went out. Twice this happened. The third time it won't go out. Noticed a tail light out, replaced it. Didn't light up. Warning indicator still on. All other lights work except the left rear tail. Can't figure out the problem. My 97 sc400 has 62k miles and never had a problem. The replacement light is 5.0 w just like the original.
