How do you replace third brake light bulb on 87 corvette?

well if you have a coupe just raise the hatch and under the breaklight there will be two torx bolts remove them and the light will come off the glass be careful not to scratch your window or paint as you replace the bulbs,also make sure you are sitting down when you price the bulb,i paid about 7.00 apiece for mine at oriellys.be careful about how you insert the bulbs as they dont have ends like the 194 bulb does all they have are the 2 contact wires sticking out the back also use a good bulb grease when you reinstall and be carefull about taking your old bulbs out try not to break the contact wires,good luck it's not that hard just take your time and you'll do ok
