shakey tail light

I almost got the car legal today, the emissions passed, the brake works, but my wipers were old, and apperently my tail light needs securing. Trying to be optimistic, but im getting a little frustrated. New wipers are on the car now, $16.00, and I paid for the inspection, $39.75. There is a little piece of metal trim missing on my light, a piece that was in the trunk,... oops, its for the other side! No worries, I flattened it out, flipped it around, and got it to where it should fit on the drivers side now. Ill find out tomorrow if I'm right. Too wet, too dark for now. Tomorrow is the day! (fingers crossed)
