I was able to actually read the characters on my original bulb and it looks like it is 97. Most of the written info I found says a 67, only a couple said 97. Not sure of the difference, maybe light output or slightly larger globe? The lense is a frosted white glass, so maybe the brighter is recommended? Sounds like both convert to a G6. Probably not a big deal. Not really worried about having the Popo stop me for that, lol. Thanks for your response.
