Hello everyone, okay so my Honda City 2003 EXi has done 124,000km, now the headlights were showing signs of wear and tear due to debris in the environment, they had gone yellow and rough due to Oxidation.
The condition wasn't as bad as I've seen on some other cars but still I decided to clean them up 
Items Used:
- 1000 Grit Sandpaper
- Rubbing Compound
- Brass Polish
- Sensodyne Toothpaste, YES TOOTHPASTE !
So, after doing some Google research, I found out that Toothpaste is not only useful for your teeth, but for your headlights as well 
To my surprise, the result was GREAT (H)
Note: I've just finished up with one headlight, both headlights were in the same condition, I'll be doing the second headlight in the evening, will take pictures of every step as well 
Things To Do:
- Application of UV Protectant
UPDATE: Just got done with second headlight, absolutely stunning result!
