I have pulsar 180 UG4 bought in march this year, mostly I travel from home to office and back, I travel on highway while coming back to home in night and I am not satisfied with the brightness of headlight on highway so I decided to upgrade its bulb. Currently bike has 30/35 watt HS1 bulb, while searching for a good bulb I found a 60/65 watt H4 bulb on eBay. I did some google and found that I can use H4 type bulb in HS1 socket of my bike. I am a software engineer not a mechanic but I believe in "Do it yourself", because this is my bird and this task don't seems to be much difficult that's why I want to do it myself, also I will get better technical understanding of my bike which will help for any further mods. I did some research and took help of some experts online and summary of my research is that new bulb is twice powerful then existing one so it will put double load on existing wiring so if I want to use this 60/65 watt bulb then I have to do some wiring by putting a SPDT relay & inline fuse to prevent extra load on current wiring and switches. The circuit diagram for this is as below. I have taken this image from a site and I think circuit diagram for my case would be same. Everything is clear but as I explained earlier I am not a mechanic so to understand the wiring of bike I need wiring diagram of Pulsar 180 UG4.
I need guidance of experts on this forum to please guide me on this. Please help me understanding wiring of my bike so that I can do it myself.
Please let me know if what I researched is ok or if I am mistaking somewhere.
Thanks.
