First of all, that one sleek ride you got there. Mashallah

2nd ... If you want to use that H.I.D light then you will have to buy another battery with more amperage. Just like Caabli Horns/کابلی ہارن, its called Caabli Battery/کابلی بیٹری. It costs about Rs.700 - 1000 ... pure japani battery hay.
Atleast thats what i know because i've seen this issue myself.
Better wait for someone else and more experienced person's reply.
