Can your "check engine light" come on in your car because of a broken headlight
If you are looking for a place to share your travel photos and stories, then try BigRoom.
It is unlikely that a headlight would cause that.
Most vehicles have a procedure for reading a code put out by the check engine light. Something like turn the ignition on for a second then back off, then on. When the onboard computer gets the signal it will flash a sequence of long and short blinks that can be converted to a number that tells you what the problem is.
The procedure for doing that will be in the vehicle service manual or a Haynes manual for that make and model vehicle.

The check engine light indicates problems with a lot of things other than the car just starting. If your theory is correct, when you replace the headlight, the check engine should go off. If it was my car, I would want to know what the problem was before I drove it. A car with no oil will start but you don't get far with it.

I don’t think check engine light performs well on all situations. Yes it true that many engine issues can be rectified with the help of this small light but sometimes its turn-on irritates a lot especially when there is not any problem in system. In this case, I fully agree with Rob, you should buy another headlight from any dealer like http://www.iautobodyparts.com/exterior_lighting-catalog/ or other and replace it to check whether the check engine light turns off or not. No other idea seems better than this, hence I think you should go for it.
