How would you wire them in ?

I had a thought about my idea while falling asleep earlier this morning.
If you go with relays and want everything running off the headlamp switch;
-if the LEDs are low draw you can run the power for their relay from an ignition source.
-if the LEDs are high draw, you'll want to use a fourth relay. This one will carry the load from the battery so you don't melt your ignition wiring and get it's signal from either the ignition or a marker lamp. Depends how you want them to act.

If you don't control them with the ignition, you'll need a toggle to turn them off and the 4th relay will solve this.
