Aww, those LEDs are cute. Do you need anything more than the cylindrical end? Would a thin 3mm LED held a bit taller do? Unfortunately this will give you a different brightness and possibly a different colour tint. It might be worth considering the option re-LEDding the whole board, as distasteful as that might sound. |

Any chance you could use ones of a similar 2mm form factor? These don't seem quite as long I don't think, but might do the job? https://www.ebay.co.uk/sch/i.html?_osacat=0&_odkw=2mm+led+round&_from=R40&_trksid=m570.l1313&_nkw=2mm+led+round+red&_sacat=0 EDIT : I found these, which are 8.0mm high, instead of 7.9mm?? https://www.digikey.com/products/en/optoelectronics/led-indication-discrete/105?k=&pkeyword=&sv=0&pv966=282200&sf=1&FV=37%7C395219%2C-8%7C105%2C525%7C395219%2C2029%7C122870&quantity=&ColumnSort=0&page=1&pageSize=25 But I see their mcd rating is a lot larger.... How about these? A little shorter at 6mm and dimmer, but closer to the original specs? https://www.digikey.com/product-detail/en/lite-on-inc/LTL-1214A/LTL-1214A-ND/3198382 |

Thanks for suggestions. I have seen the ones with flat top. I would think they should fit, but they will look different and probably will have different color and brightness. Should be fine if all are replaced - 17 red and 5 green ones. I still hope to find Panasonic ones. |

What problem are you trying to solve? |
