How to change a tail light on Accent Hyundai 2000?

Very simple;

There are two screws on the inside of the trunk that should be easily noticable, merely screw them out and depending on which side you are changing gently push the housing away from the vehicle. it is normal to hear a "pop" noise as there are two plastic pins that keep it in in case the screws might happen to rust out somehow. BE VERY CAREFUL AS TO NOT TWIST THE HOUSING WHILE PUSHING IT OUT. You will break the housing if you twist and push, a very slight wiggling motion should do the trick if it doesn't seem to want to come out.

After you have removed the housing twist the plastic pigtail harness to the left it should just pop right out with ease. The bulbs are not hallogen so you can remove the bulb by bare hand. after its removed just install the bulb and reverse the process.

hope this helps you.
