Interesting that the middle lamp of the menorah failed at around 30 A.D. according to Jewish sources. They don't state that it happened when Jesus was crucified (they wouldn't go that far). But they do state that around 30 A.D. the middle lamp failed. History is fascinating.
"The lamps of the menorah were lit daily from fresh, consecrated olive oil and burned from evening until morning, according to Exodus 27:21."
"The Roman-Jewish historian Flavius Josephus states that three of the seven lamps were allowed to burn during the day also; however, according to the Talmud (Rashi, Tractate Shabbat 22b), only the center lamp was left burning all day, into which as much oil was put as into the others. Although all the other lights were extinguished, that light burned oil, in spite of the fact that it had been kindled first. This miracle according to the Talmud (Tractate Menahot 86b) was taken as a sign that the Shechinah rested over Israel. It was called the ner hama'aravi (Western lamp) because of its position. This lamp was also referred to as the ner Elohim (lamp of God), mentioned in I Samuel 3:3."
"The miracle of the ner hama'aravi ended about 40 years before the destruction of the Temple (circa 30 c.e.) according the Talmud Tractate (Yoma 39a), "Our Rabbis taught: During the last forty years before the destruction of the Temple(that is to say around 30ad) the lot [‘For the Lord’] did not come up in the right ...hand; nor did the crimson-coloured strap become white; nor did the westernmost light shine"(wikipedia)
