We used
these.
We modified the flashlight to skip the control board and just power the light. We lathed down the aluminum enclosure to fit what we wanted. Since this had a current draw that took us over the limit for the VRM. We had to run this off this
relay controlled by the RIO.
We had some complaints about our light earlier in the season. So, as soon as the bot fired, it turn off its light and then the operator turned it on when he wanted. We couldn't just plug this into our RIO due to the high current draw. We just wanted to be perfectly safe!
