Hello, I have to let my car light up a bit from below (of course only for show purposes 😉 )! But I don’t want to screw huge (sometimes expensive) neon tubes under my car! Would the much cheaper cold light cathodes (many use them as interior lighting or as lighting for their PC) perhaps be recommended! Waterproof I get them already, but is the light yield so good that they can keep up with neon tubes?? Has anyone ever had experience with it and can give me some advice??? Thank you
