Lights?
By now if you have been reading this post, you know that the light needs to be insulated from the frame. This device is designed for mounting on a car which has it's frame tied to the negaive terminal of the battery and therefore supplies the much needed return to battery to work. The mounting hardware is part of the electrical circuit. Under robot rules, no electrical connection can be made to the robot frame so it is important to mount this on a non-conductive matierial and run electrical through two wires. We use Lexan but almost anything works.
As to the conductive rubber, my guess is your meter was telling untruths. Check again and see the resistance between the case and the rubber ring. If it reads anything at all it is probably reads in the megohm range. For this to be considered conductive it would need to be much lower, like in the 10-100 ohm range.
Earlier teams were having problems with the light not turning and a some other problems. We found that the hardware was loose in almost all cases of light failure. Check that the hardware is tight and the light is assembled correctly.
Good Luck All
