Sprayed chrome. The final product was more reflective than the first photo. Instructions on paint spray was to spray from 10 inch distance, but that doesn't make chrome finish (photo 1), so sprayed from 5-6 inches distance, which made chrome finish.
Brake lights are normal bulbs. Now tail lights are more brighter than new ones, as i compared both.
But an easier solution is to get new lights, glasses or clean the previous and put LED bulbs. They are brighter and the DIY is easier.
Update: LED bulbs in tail lights are not good at all. Only licence plates LEDs work great.
