hey sanket, let me tell you one thing here, although this might kill the mood of yours but please do not perform a DIY on your headlamps. Our head-lamps have very hard to tackel with silicon glue which don't easily come off by heat gun. Also you have to be careful that heat is not less or not too much! Overdo of heat will also damage the HL. I would strongly suggest you to get it done froma guys who had done on FIAT before, as many guys end-up messing up with our HL.
