I just replaced my 883s stock headlight with a different one. The new one uses a 12V H4 - 60/55w

I want to take my original stock light and mount it as well, so I would be running both lights at the same time.

Could anyone help me with what I need to do to achieve this? I'm guessing I need to run new wiring from the battery to it?

My electrical knowledge is limited.

 

The simplest way IMHO is to use a relay. You can buy a suitable light relay from any auto parts store, which should also come with a simple wiring diagram, the sort of thing that comes with a pair of fog/spot lamps.

This will use your current bike wiring to simply switch the relay on and off, so the current draw is actually reduced. A new wire direct from the battery, switched by the relay, will supply power to your two headlights. There are probably instructions for using a light relay on the internet - the basics are the same for both bikes and cars.

 

both would be full power all the time?

I want to run them as if they were made to be this way. Both on low beam normally, and both on high beam when switched on.

 

Yes, just the same as a car with a pair of lights!

 

Thanks buddy, appreciate the info!

 

Post pics when all is done!

 

Will do, waiting on my new handlebars to come. This is gonna be a fun week!
