Increase your safety, while reducing your risk of a citation for a headlight outage, with the Lighting Bug Technology. Plug-and-Play technology for headlights installs between the headlight plugs into the headlights in less than 5 minutes. Automatically converts the high beam into a low beam when the low beam fails. High beam continues to function normally when switched onto High. Provides an alert to the driver by flashing converted light 3 times when power is cycled off and back on. Never drive with one headlight again!
