I received 2 part 4313 landing light bulbs through Aircraftspruce, made by Galaxy---they do not work on my Bonanza, as the thickness of the rim of the bulb is thinner (front to back thickness), and the bulb freely moves in the bracket--the older bulb (also , I believe made by Galaxy) fit well, as well as the GE bulb, both of which have thicker rims---I am not seeing things, my mechanic and other pilots confirm this, and no matter how tight I make the bracket, the bulb moves freely----Galaxy rep states there has been no change in construction in the last 7 years--interesting---Has anyone else had this problem??--looks like I go back to the more expensive GE bulb--JG Fordyce
