They were perfect for Suburbans 2mm x 10mm Interior Dome Light Spring The switch for the small round dome lights in the roof mounted rear climate control panel broke over time. I gathered the parts for the switch and couldn't find the spring. These springs worked perfectly. The light dome has now been rebuilt and is working as usual. I'm leaving this comment so folks who have a Chevy 05 with those little 3-pin switches that break can also know that these are the correct spring ratings to fix. Good quality feathers (what does that even mean)
