you sure like to ask alot of questions
I've gone through half dozen sets of LED underglow over the years. Some were dim some were intensely bright. Thy're a PITA to wire & hide the wireing properly too. And they can be pretty tacky if you don't hide the tubes . If your car is lowered you may as well say goodby to the tubes. You will eventually crack them on something. I sure did. Honestly they are a waste of money unless you have an undercarriage to show off at a car show.
This. I think underglow is a little too ricey.the amount you pay for such minimal use is what turns most off its just like nathan said regardless of what you like the cops dont like tham at all and on top of that its nothing your really gonna notice as you would be inside the car along with that you run the risk of bottoming out smashing them up or having them perfect for a long time and only turning them on when your parked with your buddies showing off your new shiny underbody...If I was there id give ya **** for not doing something else for the money.
