field: Fields describe a single aspect of each member of a table. A student record, for instance, might contain a last name field, a first name field, a date of birth field and so on. All records have exactly the same structure, so they contain the same fields.
Many jurisdictions require one or more bicycle lights to be fitted to bicycles ridden at night â generally a white light in the front and a red light at the back.
The added load generated by a set of auxiliary lights may be enough to melt the existing wiring harness carrying power to those units. Most driving light sets use an H3/55-watt bulb for illumination. Two driving lights will typically draw 110 watts of power from your bikes electrical system. Using LED or HID light systems is a viable way of controlling the amount of power your bike will be required to produce to power your additional lights.
