Here is a new way to stay visible at all times. The LEDs install on the mirror housing from the top side and wrap around the bottom of the housing. The black tube camouflages easily with your case. Lights turn on with your engine and flash with your other turn signals. No drilling for installation, and all wiring is done with OEM connectors inside which allows you to remove your mirrors as before without having a wire to connect to your Spyder.
