^^^ What he said
*EDIT*
LOL, didn't even notice it was a resurrected 10yr old thread. How deep into the archives does one need to go to find a thread that old?
Anyway, sorry for perpetuating this.

Who cares how old it is? It's an interesting solution. Rather read this than another, what should my first bike be? Or should I trade my 2 year old bike with $10k in mods and 4k miles in for the newest CVO.
I noticed my 2015 Sonic shuts the lights off when I crank it. I'm going to check my other vehicles to see if they do that.

I am glad he resurrected this - his is the best solution in the thread. The OP probably doesn't need it, but someone will. Thanks Robert Smith, please continue to give us your well thought out and detailed answers!

Thank you rob smith. Ive always wanted to do this. a break down of the steps would be nice for the thick headed diy's. What i liked about the other ideas was simplicity not just to add it but less things to go wrong with less added stuff.
welcome and thanks again!

You could run a N/O kill switch to a bracket upside down right above your compression release. When you push them down, it breaks the switch and kills power to the headlight. When the engine starts and the releases pop up, it makes the switch and your headlight comes on. Good luck.

Here is my solution. Using 8$ 5 connector automotive bosch 40A relay with chassis wiring harness, SPDT, i mounted it to the batter strap with a small bolt. The relay has a metal tab out the top for mounting, and the chassis to plug into with 12 inches of wires exiting the chassis. This makes connecting easy.
I cut the lighting fuse output wire(Blue) and connected it to the NC(normally closed) contacts so when I turn the switch to ignition, the lights come on as usual. Next, from the stater relay on the fuse block, there is a green wire that goes to the stater solenoid. Splice onto the green wire to the relay coil and connect the other side of the coil to ground.
When the starter is cranking the motor, the lighting circuit opens. When i release the start button, the lights come on and the motor is running. Now light control is automatic, and is how Harley should have designed the starting circuit in the first place. Some cars are smart enough to turn the lights off during starting, this is how they do it.
Hint - the diagnostic plug on the battery strap has a black wire in it, and is a good place to wire the relay coil ground. Also, the green and blue wires are in the cavity behind the battery, so it needs to be removed to gain access to these wires. You may want to get a copy of your wiring diagram to see exactly which wires you will be splicing into.
This mod was made on a 2007 Sportster 883.
Enjoy!

Has anyone else noticed how these new members have been resurrecting old threads from 5-10 years ago? Not bad to revisit some of these issues, but I have noticed this a lot recently.
