I only saw it as the technician for a fleeting moment as the technician and I looked at it. Once he realized it was an LED board, he snapped it back into place between the inner and outer trunk sheet metal. Basically it is a circuit board approximately 8 inches long with two rows of clear LED's. I assume the LED's on one end are burned out or else that end of the circuit board is bad. The tech said the board needs to be replaced as a unit as the LEDs are directly connected to the board as opposed to being in a socket allowing replacement. Anyone else experience this problem? I will check on the price tomorrow at the dealer naybe it will be less than I think.
