license

I'm planning on replacing my burnt out license plate bulb with an LED bulb, and I want it to be as bright as possible without modding the cover. Does anyone know if either of these two bulbs will fit...

I have an LT, and i didnt have a front plate when i bought the car. SO st the moment i have only an empty lisence plate holder screwed into my bumper... Its held in my a weird screw. If i got it off, anyone know of a cheap way to fill the holes without re doing the whole bumper?? Thankzz
