Tower Base Lights

[Radical Pi]

Hi all,

I'm working on a control system to simulate the lights inside the base of the towers during endgame. Working off of a youtube video of kickoff, I've approximated the blink rate at 15 seconds to be about 1/4 second between on and off. I'm wondering if there is a more precise number posted somewhere.

Also, according to the blue box in G02:

At 15 seconds before the end of the MATCH, BASES will flash yellow ... At 10 seconds before the end of the MATCH, when
HOSTBOTS may DEPLOY their MINIBOT without penalty, BASES will illuminate with the appropriate ALLIANCE color

However, the kickoff video showed the base flashing in alliance color. As with the above question, is there a document somewhere that I'm missing which has a definitive answer?
