Those aren't white LEDs.. they're WCH "Clear" LEDs and they will light up red when active. As for the purpose of them (except for on the mast beside the cantilever), I'm pretty sure they serve as the engineer's indication that the signals are operating.

They are so white. Check out this video and pay close attention to the light.
Light rails operate differently than freight railroads, there's usually a lot more cab signaling.
The light is a signal confirmation that the gates are down.
Here on BSDA lights flash when the gates are in motion and solid when the gate is down.
Watch here 2:52

They do the same as in Kight's video. The lights are white and they flash while the gate is lowering, and then go solid. I believe if the train operator does not see a solid light (for instance the gate is not all the way down due to a car being in the way)... they have to stop the train.

I tried to post the video, but I couldn't find it on his channel. But I never knew it was in St Louis. I was too lazy to look at it on maps.

It's like a light rail line in New Jersey that run between Trenton & Camden. The only difference is that all crossings there like the Metrolink Light Rail are Safetran. The only other thing that makes this stand out is that it is a diesel light rail.
