Halyna Hutchins Candlelight Vigil for Slain DP ... Held in Burbank, CA

Halyna Hutchins was honored with yet another candlelight vigil in the wake of her tragic death -- only this time, it was held on the West Coast ... with members of the union of which she was in.

Dozens of people came out Sunday night with lit candles in hand, congregating at the I.A.T.S.E. Local 80 building in Burbank -- the main California headquarters, which advocates for scores of creatives who work in the film and TV industry ... presumably, Halyna too.

It was a somber gathering, where folks looked to be hanging out mostly in silence ... or speaking quietly to their neighbor. Most everyone was wearing face masks. There also appeared to be some people with signs, calling for the firing of I.A.T.S.E. Prez Matt Loeb.

The union has been in the news lately ... threatening to have its members go on strike if certain demands weren't met, including higher pay. A deal was recently struck to avoid any such shutdown -- but after Halyna's death, ya gotta wonder if safety was brought up in these negotiations. If not, it will almost certainly be addressed at the next juncture.

This is the second candlelight vigil for Halyna -- there was one held last week in Albuquerque, NM ... not far from where she was accidentally shot and killed by Alec Baldwin.

An investigation continues in New Mexico to figure out exactly how this happened -- but so far, it sounds like somebody left a live round in a gun Alec was using, who pointed it in Halyna's direction while practicing a for a cross-draw scene.
