The Baal Haturim says that in the current Parshe Tetzaveh Mosheh Rabbenu’s name is not mentioned. But I heard that it is implied at the end of the parshe. ‘יכפר עליו לדרתיכם קודש קדשים הוא לה the first letters of this verse add up to Mosheh. He will ask forgiveness for us in future generations.
The Baal Haturim explains that Mosheh Rabbenu’ s name is not mentioned in Parshas Tetzaveh because he asked to be erased from your book you wrote. It looks like this is a punishment. It could be that this is a commemoration of his greatness. His two outstanding character traits are his compassion and humility. This could commemorate both as this statement above was said for the forgiveness of the Bnei Yisroel of the sin of the golden calf. It also indicates his humility feeling that he is not worthy to be mentioned. The GRA says that this commemorates his yahr zeit which is every year at Parshas Tetzaveh.
The Ohr Hachaim in the beginning of Parshas Tetzaveh says that next redemption will come because of the zechus of Mosheh Rabbenu. Learning Torah lishmah will bring Moshiach. Could be that is why his name is not mentioned. The Gemora says that Haman did not know that Mosheh Rabbenu died on 7th of Ador and he was born on the 7th of Ador. That he died on 7th of Ador he knew? The simple explanation is died then because he was born then, but the Yaaros Dvash says that right away when he died he was reborn. We get the strength to be mechadesh from Mosheh Rabbenu. It could be his name is not mentioned because this strength is hidden.
Mosheh Rabbenu said to Yisro כי יהיה להם דבר בא אלי it should have said באים in plural, but the Chasan Sofer explains that Mosheh Rabbenu said to yisro, their concern comes to my heart and I have to act on it.
The light of Moshe Rabbenu might relate to Mordechai who lit up the Jews through whom they accepted the Torah with their full heart. נתמלא הבית כלו אורה like it says היתה אורה ושמחה.
