If you're thinking of installing a landing light in your wing leading edge, ensure that the lens is blown rather than flat wrapped and reliant on the attachment screws for maintaining the curvature. See recent accident report http://www.lightaircraftassociation.co.uk/2013/Magazine/January/safety_spot_ jan.pdf where a wrapped lens cracked and resulted in turbulent airflow over the wing of a Jodel on take-off. There is speculation about whether this actually caused the loss of control and the subsequent crash or whether it was enough of a distraction for the pilot to have the same result.
