Maybe the only one that changes color with Double Bulb action.
I was originally going for the monochromatic Green. Normally Blue, Red when Brake is activated. I bought this one because I saw that it could also be made to glow in the way that
I checked before installation and found that even if the Blue + wire was left connected and the Red + wire was connected, the Blue went out and the Red light came on (there was no indication that the Red light came on while the Blue was on). (It did not happen that the Red wire came on while the Blue wire remained connected.)
Currently, installation on Motorcycle is Can switch Red⇔Blue at will." I have done this with Wiring, and of course it switches and lights up properly.
Similar products RIBLE." The price is about half of the price of the "K" series, the texture is not bad, and I think the cost performance is very good.
However, whereas the Acrylic board of RIBLE was good because the edge portion was cut at an angle so that the luminescence of the edge portion could be seen well when viewed from directly behind, this MADMAX board is normally cut vertically, and visibility when viewed from directly behind is inferior.
This reduced it by one star.
As is the case with both RIBLE and MADMAX, we found that during the daytime the Impact was not as great as the Image of the product.
Unless you drive a lot at night, you should not expect the product Image if you only ride in the light. (The luminescence of the product itself is not bad)
