I bought a set I think is the same as the ones from Suncoast but they are $23 delivered free shipping for the set instead of the $35 plus shipping that Suncoast charges. Whatever you do, I don't suggest the LED Festoon type bulbs as there's not enough room in the housing for the heat sink to do its job and the clear plastic cover ends up browning up. Get the entire led housing that they sell on EBay. Just search for LED License plate lamp Porsche 911 / 993 996 Boxster. They update the look of the car, and are easy to install...
Top is old incandescent bulb, and bottom are the new LEDs...
