my yukon headlights had led drop in bulbs when I got it. they seemed fine, but I replaced the whole housing soon after.
you should check the amp draw of the bulbs you're trying to use. it should be under the fuse by atleast 75%. so like a 10amp fuse circuit will usually only run 6-7 amps max, before going to thicker wire and higher fuse. running a 10amp fuse with a 9-10amp load usually leads to hot and or melted fuse terminals. gotta remember the fuse uses a tiny wire is meant to burn quickly in a short. running one right at its rating makes for a lot heat across that small connection
