Yes i have heared that here also!
But I know one guy, he has a Getz(red), Skoda Octavia(black), Civic(white), Accord(latest)(black), Innova, and many more(all cars last four dights of the number is same), with many customs on each ride, he has this laal batti on all his rides, not the permanent ones but the portable, he keeps on the dash board and when needed he puts on the top! He is not a VIP person but then also he has it!
Now i am wondering HOW??
Only a VIP's car is supposed to have, that too of some selected ones!
