A long time ago in a galaxy far away I was ldg. at MYGF in my trusty Twin Commanche. Sometime during the flight I must have turned on the nav lights and didn't catch it. Upon throwing out the gear I did not get the usual little green lights. I went through the checklist pulled back on the throttles, checkall the things you can think of, opened gear extension doors and all,followed up witha tower flyby and then found the @#(&(^ switch for the navlights "on". Autodim to indicator lights rendered the lights too dim to see a difference in the bright Bahamian sun. Best to check out particular airplane's quirks before assuming one way or the other is best.
We used to pull the bezels off the lights in the CV's to check the lights in the daytime. Landing gear up is not a career plus and you'll need 59.5" to taxi.
