need help, electrical system question
Can one of you, who know what you are talking about, tell me if I can substitute the 35 watt and 50 watt bulbs in the dual bulb headlight with two 60 watt H9 bulbs?
Thanks up front,

I like the "who know what your are talking about" part. Nails it down pretty good. Hope you get an accurate response. Wire size and base of the bulb would be in the controlling factors, of which I have no idea for your bike. Good luck, and more light to ya!

I dont think so, the systems only designed to put out the required watts, your 60w bulb wont get the watts it needs and will not be as bright, or may not even work at all. Also the fuse and wires weren't designed for that load either.

As Glebo mentioned the system is designed for output current based on wattage. That being said a change that you are speaking of would cause a change in the light fixture, wiring, fuse, and possible switch.
If light is the issue find a bulb that has a high number of lumins per watt. All systems will remain thesame, the wattage the same but the brightness of the light will be greater. You may also want tochange the colorof the bulb output. Go with the blue tinted or whiter bulbs for more light.

It could be done, however most newer lighting systems use minimal wire at best for lights, by putting a larger load on the higher wattage light you are going to be taxing the electrical system. It can be done, but you need to keep an eye on it. I have seen where the connector melterd to the bulb. Then again I seen everything wok aok.
Best advise is to try it, but keep a keen eye on the wires and the plug.
.........Then again I might not know what I am talking about

I believe the dual bulb fixture also contains a diode rectifier bridge which allows both bulbs to function in the high beam position. Too much current might destroy the bridge unless you find a good way to heat sink it (it has a hole in it, I believe). Not only might you be stressing the bridge, but, as others have stated, the wire might get a bit hot and either fail or glow from the excess current. Heat inside the fixture will also increase about 40% - plastic might melt. I'd go for additional lighting. I have personally seen excellent results using these --->

RE: need help, electrical system question
To get DC current divide watts by voltage. 50 watts at 13 volts is 3.85 amps. 35 watts at 13 volts is 2.7 amps. For the 2ea 60 watt lamps you'll need about 4.6 amps each. What is the wire size and fuse rating? There is an "in rush current" with lights, so to be safe you would probably double the requrement. So call it 10 amps each for the 60 watt lamps, meainng a wire that will carry 10 amps with a 10 amp fuse.
Like the others said, it would probably work, but may run hot, and/or overheat wires, switches and sockets.
