Simma, gents.
Not a fan, but as already mentioned they look like a conglomeration of clears & red/clears for a teg. I just see them as a sore thumb on the car... it's like everything flows with the car until BAM!... taillights all bright and out of place. And what's the point of having half of an illumiated section red and the other clear? Just doesn't jive for me.
Anyhow, try ebay.. probably your best bet if they are actually mass produced.
