for all those in lahore who want to install HID or increase the intersity of their headlights can contact a guy near shah noor on multan road. he goes by name 'karachi wala ustad'. he has excellent electricians who can do pretty much anything with ur bike as far as lights are concerned. he has bigger batteries as well. i myself got a pair of fog lights installed from him a month ago. now when i switch on those two lights, along with my headlight i get a high visibility at night. he installed the fog lights for a total of rs.1000 (including labour), and he said that his price to install a bigger battery would be rs1500 (total including labour and battery). His work is neat and very professional. Dont expect the place to be very big, it actually looks like an ordinary shop, but his electricians are really good. dont get anything else done from him apart from electric work. his contact number is:
karachi wala ustad : 0331-5650966.
one thing that i would like to advice is that make sure u set the price final with him before he starts any kind of work on the bike and make it certain that u will not pay a penny over the agreed price and also try to bargain hard. i got my fog lights installed for rs.1000, but with better bargaining skills i think i could have gotten him to do it for atleast rs.800
