Bulb W5W 12V W2.1x9.5d, aftermarket

Bulb W5W 12V is an aftermarket part for the lamps of JCB and other construction machines.

W5W is a small 5 W wedge bulb with a W2.1x9.5d glass base, used in side lights, number plate lamps and instrument lighting. Wedge bulbs are pushed straight in and pulled straight out. The bulb voltage must match the machine's electrical system: a 12 V bulb blows at once on 24 V, and a 24 V bulb glows very dimly on 12 V. The bulb is chosen by its standard designation: type, voltage, wattage and base. If the wire ends of a wedge bulb are bent it will not make contact in the holder, so straighten them before fitting.

Fitting

Before changing the bulb, switch off the circuit and let the lamp cool. Push the bulb fully into its holder, and never touch the glass of halogen bulbs with bare hands. After the change, switch the lamp on to check it works and that the lamp body seal is in place.
