I tried ordering a colored lens version for demo and they said they are expecting them to be ready towards the end of the year.
Dave: You can not activate each color separately. Their is only 1 wire for flashing, however brake, tail and turn/steady functions can each be setup to light up the full lighthead, just the right, or just the left half. They have good off axis lighting but are bright head on. I think they would be alright to use behind the grille. I have the 7x3 and 6x4 models. You would have to figure out a mounting solution though since their L brackets would not work with the wide-lux series without modifications.
