I found these two lights hanging around behind my license plate. they are split and then connect going into the rear of the car. where do they go? are they for above the license plate? i cant seem to find a place that will hold them.

Do they turn on and when? Sounds like their for the plates?

they turn on when the lights are on.

and if so, where do they go?

they are most likely your tag lights

These are your Lic plate lights, but sounds like someone lost the lenses that they go in. The lenses have one bolt on them and screw in the top. If you reach up in there I'm sure there is two holes where these were mounted. (that just don't sound right) reach up above lic. plate toward yourself! You will need to buy the lenses they go in, or find em at a local Bone yard.
