Wiring a roof spotlight bracket clean

TL;DR — direct answer

Run a fused relay circuit from the battery, switch it on a keyed source, and route the harness down the A-pillar behind the trim. Ground to bare metal and heat-shrink every joint.

How to choose

Use a relay so the switch only carries trigger current. Fuse within 15 cm of the battery positive. A keyed ignition source for the trigger stops you leaving the lights on.

Route the harness behind the A-pillar trim and along the headliner edge to the bracket. Ground to a sanded, bare-metal point and seal every connection with adhesive-lined heat-shrink.

FAQ

Do I need a relay?

For anything beyond a small pod, yes — it keeps high current off the switch and out of the cabin.
