Dedicated loom to power two front spot or fog lamps on Austin Healey BN1–BJ8. Finished in period-correct cotton-braided covering with a discreet relay and inline fuse for safe, reliable operation.
Yes: fits all Austin Healey BN1, BN2, BN4, BN6, BN7, BT7, BJ7, BJ8. Connects to the car’s main harness using standard bullet connectors. Includes a relay to supply two front lamps.
Compatible lamp assemblies (all supplied with bulbs fitted):
Route the loom along the front panel, securing it clear of heat sources, the fan, and moving belts. Ground the black ring terminal to a clean, bare-metal chassis point. Use the supplied earth leads at each lamp; do not rely solely on lamp casings or painted brackets for return. Connect the red/yellow feed to the floor dip-switch main-beam circuit, or to a separate dash switch if preferred. If a rear fog lamp is fitted, the blue/yellow lead requires its own dash switch. Mount the relay/fuse carrier upright and sheltered to minimise moisture ingress, and protect any panel pass-throughs with grommets.
Combines modern electrical protection with period-correct presentation, avoiding overload of original switches while keeping the bay and front panel visually in-keeping with factory looms.

Two. It is designed to supply a pair of front spot or fog lamps from a fused, relay-controlled feed.
Front lamps can be triggered from the main-beam (dip switch) circuit or a separate dash switch. A rear fog lamp, if fitted, needs its own switch on the blue/yellow lead.
Yes. The loom uses standard bullet connectors to mate with the main harness. Basic crimping tools and good earth points are recommended.
