When driving where it's actually dark (as opposed to in the city), I really
hate having any kind of bright indicator lamp on where I can see it.  Your
eyes respond to total light received, so a light even in your peripheral
vision will cause your irises to close and make it harder to see the (dark)
road).  Some of my cars even have a band-aid stuck over the high beam
indicator!

A better alternative might be a simple 12v buzzer and a diode, connected so
the buzzer only comes on when the lights are on but the ignition is off.  It
could be hidden under the dash, so not take up valuable panel space either.

Add another diode, and the same buzzer could indicate when you've left the
headlights on.
