We observed females from distances of 3-20 m with binoculars and a headlamp dimmed with a rheostat to the point where the female was just visible. |
Our maintainers determined recent rain, combined with chafed insulation on the wiring behind the formation-lights rheostat, had created a short circuit. |
Maybe evolution has endowed us with the ability to turn back our rheostat faster, to not always charge ahead after one all-consuming thing. |
An ideal situation would be a very bright bulb attached to a rheostat, so that the desired illumination level could be chosen as required. |
Handle with rheostat for infinitely variable regulation of light intensity. |
If your bathroom is bright, consider installing a rheostat or washing up by the light of a night light. |
