Nice work, however try adding a corner bulb as it will enhance the brightness a lot.
I used this chrome paint back in '08 on my car but felt that taxi wali feel with too much chamak even when the lights were off so a year back as per @Xulfiqar 's advice I opened the lights, painted the dome white with auto-color, added 5W corner bulb, sealed the lights properly and the results were zabardast.
Have a look.
These first two with the lens just placed (not attached) and the second last is with just the back lights and the last one is with the brake.
I was so happy with the result of white paint that later on I did the same with the licence plate lights housing.
Did malta lights had this type of translucent glass to spread light?.
It must be there, because if this is not present, light won't be evenly distributed.
Try them in the back lights and let us know the results.
