These look pretty similar and may be worth investigating at lower cost.

The way I read KBMOG's lamps the price is for a pair , where as yours is for a single so actually more expensive ?
I think the idea is very good , but how do you wire the led part up ? do you just connect the led wires to the existing side light feed , or do something special to protect the leds from overcurrent etc ? electronics is not my speciality, but I believe you have to protect leds from too high a current or they easily go pop !
