The Link pro meter by Xantrax does not light up at night unless you manually press on the meter. You can program it to have the light on all the time but this would be on 24/7. I added a blue LED strip to light up the instrument panel so I can see the Link Pro Meter at night. I like the look but may need to tone it down a bit as it's a little bright. I need to paint my dash panel flat black to reduce reflections. It is also a source of glare when the sun is reflecting off of it.
