When I got my 2019 Slingshot, I said the first thing I would do to it was upgrade the headlights to LED. Finally did that. Simple enough installation but I'm proud of myself for opening the hood. I'd upload before and after pics but importing a pic always comes upside-down. I used the T3 and T9 bulbs from Slingmods.
The ST Owners Club used to call these mods "farkles." Not sure if there is a name for it on a Slingshot. I also kinda feel bad that I haven't named it yet. My ST-1100 was called "STarscream," then that one got wrecked so I called the ST-1300 that replaced it "STarscream's GhoST." The Slingshot? We have just been calling it "the buggy."
