	The current rating on the bulb determines the amount of current the bulb will draw used at its correct voltage rating. The higher the current the brighter the bulb will glow (and shorter the battery life will be). Clear glass bulbs are the most common but coloured glasses are available as are flashing bulbs but at a higher cost. Bulbs are usually screwed into a bulb holder which incorporates terminals for connecting wires and to aid in the physical mounting.

			The voltage and current rating is usually stamped on the side of the body of the bulb. The voltage rating of bulbs in normal use are 2.5, 3.5, 6 and 12V. The correct voltage rating must be used although there is a certain amount of leeway. For example a 6V bulb could be run from a 4.5 volt battery but with reduced light output. Also a 6 volt battery could run a 3.5V bulb causing it to glow brighter and with likely shorter life.


			The current rating on the bulb determines the amount of current the bulb will draw used at its correct voltage rating. The higher the current the brighter the bulb will glow (and shorter the battery life will be). Clear glass bulbs are the most common but coloured glasses are available as are flashing bulbs but at a higher cost. Bulbs are usually screwed into a bulb holder which incorporates terminals for connecting wires and to aid in the physical mounting.
