I didnt take them apart, no need, I went to Walmart and bought Transparent Red Paint then Painted the Housing where it was clear Red, The only downside is my Reverse Lights are Red... It only cost me $1.58 and it made the car look way better IMO of course.
Its holding up great, I did it about 9-10 months ago and it still looks like it came factory which is surprising since it held up through the winter. Nah I didnt clear coat at all, I just put 2 coats of the paint on and its still there no fading or chips yet even when the lights are on it looks red not that pinkish color you get sometimes.
or how about this one...the light on the left w/ only the top signal circle tinted red, or the one on the right with only the bottom reverse circle tinted...
I think the all red looks the best... really good in fact... but if you wanted one of the last two I'd pick the left light. It doesnt look that bad either..
