WTB: LED bar from P10 T-spoiler

I have a P10 G20 (95) with the T-spoiler with the integrated LED 3rd brake light. Recently I found that some of the LED's have burned out over time and I want to replace the assembly. The dealer wants over $200 for this little light bar. Their parts guy even laughed when he saw the price for it. (It's just a sealed little unit with two wires) Does anyone know where I might be able to get an aftermarket part for much cheaper that the ridiculous $200+?

Any aftermarket shops out there that sell the LED light bar?
