1. Remove the taillights

2. Now, separate the taillights into 2 pieces (face of taillight separates from taillight housing)

3. Then take out factory reflectors

4. I bought (ceiling light) reflector material at home depot to make replacement reflectors.

5. Now, take paper and made pattern of taillights from taillight face shield.

6. Then copy the pattern onto the ceiling material.

7. Cut out the pattern (I used a box cutter to do it, so I didn't chip the material)

8. Now simply insert new lens into the taillight face shield. (I used "goop" glue and glued corners.)

9. Now put face shield back on housing.

10. And finally, go buy some red tailight bulbs and put tailight back in car.!

The finished result should looks like this: Figure 1
