streetglow OPTX was tubed so you could see them in the back. That was fail haha but the tube protects the lights so its a trade off. I drove the car 50,000 miles never had the underglow get damaged or go out on me.
Edit: I even hit a racoon doin 75 and destroyed my front bumper, but guess what was still goin... OPTX led's haha I couldn't believe it. Didnt even crack!
As a sociologist I gotta ask, when and why did under glow go out of style?
