I'm very excited about our new BriteCaps EVO 2-Color Pop Bumper LED with "ICE" frosted caps. Rarely in pinball do you see pop bumpers having two colors within it. These new LEDs have a circuit board with one color around the perimeter and a second color in the center that can stay on or "flash react" with vibration sensing technology (Patent Pending). You can use clear pop bumper caps, or better yet, we now have white frosted ones that produce a nearly "neon" look. This is a new product and for now we only offer two popular color combinations...red with blue centers and purple with green centers. These are available at Pinball Life's website in the BriteMods store. You can choose 2-color LEDs and white caps from their drop down menu. Let me know if you have any questions or suggestions!
