Abstract: A light emitting attachment device for driver helmets that visibly indicates to the driver selected vehicle conditions on a race car and a motorcycle. The helmet has a visor with a clear flexible tube supporting an array of single colored LEDs clamped inside the visor. The helmet is plugged into an shift indicator rpm light on the vehicle. When the shift indicator switch turns on, the LEDs all light up indicating to the driver when to shift the vehicle into another gear. The device can also be attached to dash board warning lights such as those for engine temperature, oil pressure, and the like. When the dash warning light comes on, the LEDs light up on the visor indicating to the driver the warning condition. The LED array can include a first set of LEDs (such as yellow ones) dedicated to being activated when the shift light comes on and a second set of LEDs (such as red) that turn on when an engine warning condition exists.
