I saw it somewhere on CLub Lexus in a image, but can't find it anymore. Does anyone know here to buy it? Mine bamboo pearl.

Thanks

 

You can get them at www.bumperplugs.com.
I have them on both my cars.
Although mostly aimed at Porsche, they seem to have all the Toyota colors (which includes Lexus), so call if you can't find a match on the web page. Color charts and all those codes can be confusing, but the people there are very helpful.
