HIDs will work only with those bikes that have their battery above 7aH. If your bike’s battery is not upto this mark, then don’t consider HID.
There are two types of headlamps in Indian motorcycles. Running on AC or DC. If your bike’s headlamp fluctuates with your accelerator – dim at low RPM, bright at high RPM – it is AC. If it can be switched in without the bike kicked on, it is DC. If your bike has battery less than 7aH and runs on AC current, then do a simple mod. Disconnect the pilot lamps, and speedometer lights. This will give you additional 10-15W current at disposal. Then switch your headlamp to Osram Silverstar, costing about Rs. 180. The change in the quality of light is easily noticeable. You won’t be able to see the speedometer now, because it is all dark, but better to see the lit road and dark speedometer than the other way round.
If your bike is DC and/or has battery above 7aH, go for HID. There are many tutorials online, on xbhp.com forum, to tell how to convert your AC bike to DC. But if you are one the technically challenged ones like me, and don’t have access to any good mechanic, the instructions can be quite hard to follow. In that case, just go for HIDs and use common sense. HIDs require a lot of current, and if the battery runs out of juice, then the HIDs go kaput. Thus, you will have to reduce the load on battery by other mean. Easy ways will include sacrifice of thumb starter. You will have to let go of this comfort, or atleast limit its use for urgent occasion only. Starter pulls up a great amount of current from the battery, which can now be used for powering up the HID. Second: the battery is getting charged constantly when you are riding, its charging speed directly proportional to the riding speed. Generally above 3.5k RPM, the charging speed of the battery matches the discharging speed by the HID. So if you are on a highway ride or a speedy ghat ride at night, you can use the HID without any worry for long hours.
