This song is Spitz's 12th single released in 7/7/1995 and reached the 2nd spot on Oricon's weekly charts, selling nearly 100 million copies. The title when written in kanji is "涙がキラリ☆". The members decided to add the star into the title due to the single's release on the same day as the tanabata festival, in hopes that the song would help liven up the festival even further.
*Tanabata is a Japanese star festival.
I believe the song is about the legend behind Tanabata festival and also it's festive atmosphere. It celebrates the meeting of the deities Orihime and Hikoboshi (also known as the stars Vega and Altair, respectively). According to legend, the Milky Way separates these lovers, and they are allowed to meet only once a year on the seventh day of the seventh lunar month of the lunisolar calendar.

The bat flies into the dusk the moment it awakens As if to not let it go out, i'll keep the key in the keyhole
Now, i've decided to let the memory of you stay in a corner My gaze remains timid As we stare at each other until the night turns to dawn
The same tears are sparkling Even if I were to be an angel The two of us are still waiting for a star The sadness tightens inside us A faint light connects my heart to yours
A summer-time landscape drifts in the air From the sleeves of a yukata The skeleton floats by and disappears Beating to the rhythm of love
The scenes in my memories are flashing Even though everyone's illusions will change This planet that does not know anything Keeps spinning, oblivious to our world
The same tears are sparkling Even if I were to be an angel The truth is, I kinda want to touch you Bring on the southern wind Burn this time that will never return into my memories
The same tears are sparkling Even if I were to be an angel The two of us are still waiting for a star The sadness tightens inside us A faint light connects my heart to yours
