Thank you for viewing. This was installed on a 30 series Vellfire, but I think it can also be used on the 40 series. The VELLFIRE LED emblem lights up blue when the small lights are on and red when the brakes are applied. Personally, I think it looks pretty cool. It's the type that easily attaches to the rear window (can be used on vehicles with tinted windows) with suction cups. Wiring isn't too difficult if you connect it to the rear lamp, but I can't provide support. Mainly black with a design that emits blue and red light. - Model Name: VELLFIRE - Color: Black - Light Color: Blue when small lights are on - Light Color: Red when brakes are on
