再见了我亲爱的，有一天我会带着一身光彩来找你。翻译成英文

我没水平，不过也出一个供参考。

Farewell,my dear,someday, may I come with a luster to be back with you.

good bye my love. i will be back for you decently one day.

So long, my dear! there will be someday i come for you with luster.

地道点的口语是:

bye now my dear, I'll be coming back with a brilliant soul one day.
