Hi! Can you tell me the difference between the two types of light bases you show above? The situation I have is I bought a set of the clear LEDs figuring we could get replacements since my husband prefers the colored ones. But, once we started pulling them apart, we found the different sized bases and the only replacement ones I could find had the short stubby base. Are they interchangeable if we pull the bulb out of the base? Do you have any suggestions for us? Thanks for any help!
