Those little round lights in the main headlights are optional 'Accent' lights, and not there on all RT models. The similar looking little 'lights' in the fog lights are completely fake and I don't believe anyone has really been successful in getting lights, LED or otherwise, into that spot in the fog light assembly - the big fog lights, sure; those little 'lights', nup! As for those little 'Accent Lights' in the main headlight housing, generally, if you want them, you would've needed to specify them when the Spyder was being made! If that didn't happen, then you'll either need to source something after-market or you'll need to find and buy the OEM fitting that Nazdackster mentioned...
BUT, even if you can find a set of those Accent Lights or an A/mkt equivalent and buy them, while you might find that the wiring is there to plug them into (it is there on most 2010-2018 RT's) it's pretty rare for any Spyder that came from the factory
without the Accent Lights to actually have the holes that the light itself shines out of! Instead, most RT's up until 2018 that came without them had a shiny plastic 'fake light'built/moulded into the main light assembly that looked like a lens, but wasn't; so you would either need to buy a complete set of headlights that already has appropriate holes and fitting; or you'd need source the light kits, and cut that shiny plastic fake/lens cover out, something that's easier said than done (do you really need to ask me how I know that?!

)
