KS, not sure on the swap out, but most of the cost is in the circuit board controlling the flash etc. IT was a nice unit, but if you count the LED's on the site there arnt very many. Then if you watch the different flash patterns only 3 or 4 LED's are being used as turn signals. imagine 3 of your monitors LED light blinking in the son. Not trying to shoot down a good looking idea but also want you to be happy/safe!
