I use a lot of these 3 color LEDs that have 4 posts. I typically only use two colors so I end up trimming off one of the posts.
I also mount these LEDs using a 5mm metal bezel but the plastic collars that come with them only come with two holes so I manually poke a hole for the third prong to fit.
Does a product exist that accommodates three or four probably LEDs for a 5 mm bezel. Sorry if I’m not calling things by the right name.
