It drives me crazy that so many drivers are on the road with multiple signal/head/brake lights out. Since there is no universally accepted way to communicate to them that they have a missing light (or have not turned them on), I propose a colored light that can be activated from the driver's seat that will be universally recognized as a "check your lights" signal. I imagined something like a colored light flashlight - blue perhaps, that you could direct forward or backward (for cars in front or behind you with a light problem). Similar to baked Car Lights idea (see below), but with a light instead.

Car Light http://www.halfbake...m/idea/car_20lights
Hand signals for cars whos lights are out. [trekbody, Oct 20 2004]

I always thought this would be best communicated by having a switch that allowed me to turn off one of my headlights briefly. It's probably best if it's a momentary switch so it can't be left off accidently.

A flashing "new auto" light. "Come door ding me, I'm new!" it flashes.

Hmm...perhaps we could just throw Mag lights and rolls of duct tape at other drivers as a hint?

How do you communicate to someone that their 'check your lights' light isn't working?

There already is a sign:

<hi-beam flash> "Bugger, the cops! Oh wait, I haven't turned my lights on."
