Default no headlights on 2007 ST

New to me bike. It was purchased with a JMCB 2003 installed. I have a Bluetooth headset so I spent Sunday morning tracing wires and removing the hardware. Now my headlights won't illuminate. The marker lights are on and the blue high beam indicator comes on in the dash when the high beams are switched but no lights. I found two fuses labelled as head lights but neither were blown. I lubed the switches on the right and left handle bars just in case. I fiddled with the dimmer button as well since it appears that the headlight wiring goes through everything and traced back everything it took off just in case. Any ideas? The, Ken

Don't suppose you dislodged the connectors at the backs of the lamps? After changing mine the right side has developed a habit of working loose.

Is your kill switch on the right handle bar off?
I do not use the Honda wiring to light off the headlights so I can't check this to see if the kill switch in the off position will not power up the lights. Simple enough to look at and see.

Clearance lights use the same wiring as the tail lights.
The will light independently of the head light.
If you clearance lights are on your tail lights should be.

When pressed the start button shuts off the headlights. Stuck switch?

The sockets to each headlight bulb are "pinned" requiring you to press both sides of the connector to remove them.
Seems like something you would remember if you had pulled the socket removing the headlight assembly, if you did remove it.
Pull one or the other and meter it to see if you have power at the socket with the key on.

One other item on the headlight assembly is the "Tip over switch".
Make sure you reconnect it if you ever remove the headlight.
Not much will work if the tip over switch is unplugged, the system thinks the bike is laying on it's side and will not power up much of anything. This one can cost you serious time spent in checking all the connections for the recently installed add-on's thinking the problem is there.

Dirty starter switch? If the start switch does not fully return after pressing, the headlights will remain off.
