I backlit the side intakes many years ago, but have never wired them in or used them aside from these photos. The forum consensus was that they were tacky, but they’re not. They’re awesome. I need to get them wired up.
They are very subtle...I have them on a larger (ohms) resistor, so they are quite dim and give just the slightest green glow at night.
They are also technically illegal, which is why they’ve never been hooked up.
