The International Cessna^® 170 Association

Did Cessna change the design of the landing light brackets on the B models? My parts book shows a two-piece bracket for each light, mounted with screws on springs. The light fits in between the bracket channel. I've seen this set up on the '56.

My '54 has a one piece bracket on each light and no springs are behind the brackets. It doesn't appear to be adjustable because the light is held in place only by tightening the bracket down all the way.

You might have the L-19 light bulb component as I did in my first 170 with the L-19 wings. They were different in that you could not easily change an individual bulb as both of the bulbs where encapsulated in a metal frame riveted together and thus not adjustable between each other. I don't remember if the entire bulb assembly was adjustable. The only way to change light bulbs was to drill out rivets to disassemble the light assembly.

This one has two separate bulb retainers. There's a piece of rubber that cushions the bulb against the retainer but each retainer just screws down flat.

To answer your original question... Yes, all the metal winged C-170s used two channel-shaped retainers per lamp. (I am not certain what you might have in yours but it doesn't sound "official".)

10-4. I'll show y'all what is on mine when I go back to the hangar.

This is what was in it.

I wonder if those are off of a fixed position landing light, like in a nose mount?

I took those off and put the correct ones on.
