Specified for use as a bulb holder for instrument illumination and for the pilot bulb in the headlamp, this assembly is complete with the single lead and bullet connector fitted. Can be used with either 988 6 volt or 989 12 volt single-contact bayonet bulbs.

This new production genuine Lucas bulb holder is a faithful reproduction of the original design. There is a fixing point for an external ground wire on the base of the socket.

Will fit tightly in the 16mm aperture in the glass headlamp reflector or instrument housing as the splayed “teeth” around the diameter of the socket retain the bulb holder into the mounting holes.

The bayonet-type bulb is pressed into the socket and rotated clockwise once the pins are aligned in their grooves. The wire is connected to the lead from the main harness, or in some cases, directly to the headlight switch. Refer to the wiring diagram in the workshop manual for more details.

Please Note: due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
