Wow, never thought about it that way. English is not our native language but, for our defense, it's the first time that somebody made that remark.

When you said that you were using the hydrogen as a fuel source as well, I also thought of the negative connotation of igniting it with a "lighter".

This connotation is too bad because HyLighter is a great multi-way pun (highlighting defects; going high in the air; with a lighter-than-air vehicle; based on hydrogen).
