Those LED's are for single beam headlights, so if your vehicle takes a single filament bulb that LED they should work fine.
Otherwise I'd be worried about them over heating, 6 watts of heat is not a lot but over time, in an enclosed space, they are going to get hot, the version that is sold on Amazon for $45 has a single review saying that they burned out after 10 days of use.

shows some that have all three contacts, of course there is no saying how well they really work and a number of them require you to buy 29 or 32 of them at a time.
