I recently purchased a TAF and am slowly starting to clean it. All of the incandescent bulbs work, but quite a few of them have a blackish haze on the top of the bulb, which I understand means that they may burn out soon. As I think about replacing bulbs and making additional lighting mods (it has no mods whatsoever), do people have advice on whether to switch to LEDs or stay with incandescents? I've seen newer machines with LEDs that look sharp, but I am not sure if this "modern" look is a good fit for an Addams. Thanks.
