Use this as an added parking/brake light, or a sequential/interior accent light. The bar is approximately 17" long and has 20 red LED's in it. It comes with mounting screws and an on/off switch. Very versitile product lots of uses!

There are 3 wires coming off of it that will decide how it will function. One is always going to be a ground wire, the other two will depend on how you want to use the light. Put power to the white wire, and you get half brightness all LEDs constantly on (ideally connect to parking light wire). Put power to the yellow wire, and you get full brightness back and forth scanning (ideally connect to brake wire). Twist the yellow and white together and connect to power for all LED's constantly on at full brightness (ideal to use as an interior accent light).
