Wanted to use a diffuser on the lithophane night lights I made from lithopanemaker.com and I couldn't find any. So here they are. its my very first creation so I'm definitely not an expert at this but these work great. You have to pull off the plastic ring right below the light bulb and then press fit the diffuser on. Its a tight fit but they do fit. Make sure you line the seam up facing the wall and not the lithophane.
