Hey Guys, I'm doing some amateur electrics at the moment on my SR400, and installing some different blinkers. I'm earthing the blinker on the frame itself, but running from the positive to the battery are these little doobiwhackers... They say: "Royal 661 5W 1(Ohm Symbol) J" Now my question - these heat up a far bit when using the indicators, quite hot to touch. The engine wasn't running when I was testing this. Is this normal? They were wrapped in factory gaffer tape when I started. Oh, and what are they? Any help would be greatly appreciated!
