Do yourself a favour and grab a couple of packs of silicone earplugs at any pharmacy. They're about five bucks a dozen. They're for kids but work great as I too am a light sleeper and use them all the time. you can combine one and a half to make a bigger one if needed.
There's some orange ones too.
Just make sure your hands are clean and oil free. Oh, and your ears too.
